This function was names slightly confusing, as it returns a fakeStore,
and it didn't do any constructing, so didn't provide value above just
constructing the type.
I'm planning to add more functionality to the fakeStore, but don't want
to maintain a full-fledged constructor for all of that, so let's remove
this utility.

Before this change, the config-file was always updated, even if there
were no changes to save. This could cause issues when the config-file
already had credentials set and was read-only for the current user.
For example, on NixOS, this poses a problem because `config.json` is a
symlink to a write-protected file;
$ readlink ~/.docker/config.json
/home/username/.config/sops-nix/secrets/ghcr_auth
$ readlink -f ~/.docker/config.json
/run/user/1000/secrets.d/28/ghcr_auth
Which causes `docker login` to fail, even if no changes were to be made;
Error saving credentials: rename /home/derek/.docker/config.json2180380217 /home/username/.config/sops-nix/secrets/ghcr_auth: invalid cross-device link
This patch updates the code to only update the config file if changes
were detected. It there's nothing to save, it skips updating the file,
as well as skips printing the warning about credentials being stored
insecurely.
With this patch applied:
$ docker login -u yourname
Password:
WARNING! Your credentials are stored unencrypted in '/root/.docker/config.json'.
Configure a credential helper to remove this warning. See
https://docs.docker.com/go/credential-store/

$ docker login -u yourname

This message resulted in code-lines that were too long; move it to a
const together with the other hint. While at it, also suppress unhandled
error, and touch-up the code-comment.

Deprecation comments must have an empty line before them, otherwise tools
and linters may not recognise them. While fixing this, also updated the
reference to PromptUserForCredentials to be a docs-link to make it clickable.

If restoring the terminal state fails, "echo" no longer works, which means
that anything the user types is no longer shown. The login itself may already
have succeeded, so we should not fail the command, but it's good to inform
the user that this happened, which may give them a clue why things no longer
work as they expect them to work.
With this patch:
docker login -u yourname
Password:
Error: failed to restore terminal state to echo input: something bad happened
Login Succeeded
We should consider printing instructions how to restore this manually (other
than restarting the shell). e.g., 'run stty echo' when in a Linux or macOS shell,
but PowerShell and CMD.exe may need different instructions.

we don't support empty passwords; when prompting the user for a password,
we already trim the result, but we didn't do the same for a password that's
passed through stdin or through the `-p` / `--password` flag.

- move trimming defaultUsername inside the if-branch, as it's the only
location where the result of the trimmed username is use.
- do the reverse for trimming argUser, because the result of trimming
argUser is used outside of the if-branch (not just for the condition).
putting it inside the condition makes it easy to assume the result is
only used locally.

move the "post" check for username being empty inside the branch
that's handling the username, as it's the only branch where username
is mutated after checking if it's empty.

remove isDefaultRegistry and inline it where it's used; the code-comment
already outlines what we're looking for, so the intermediate var didn't
add much currently.

This function has multiple conditional branches, which makes it harder
to see at a glance whether authConfig may be partially populated. This
patch instead returns a fresh instance for error returns to prevent any
confusion.
It also removes the named output variables, as they're now no longer used,
and the returned types should already be descriptive enough to understand
what's returned.

Remove the registerCompletionFuncForGlobalFlags for now, as
the error it returned was ignored, so it didn't add much
benefit, other than abstracting things.
Split the underlying completion-functions to separate
functions, and add some basic tests for them.
Remove the completions helper, as it now didn't add much,
and it saved having the dependency on the package.

Prevent some tests from failing when running from a pre-compiled
testbinary, and discard output to make the output less noisy.
