cli/command/system/runInfo: set negotiated API version when available

The current logic was ignoring (e.g.) `--format=json` formats, and was
only setting the negotiated API version if no format was specified.

While we do want to avoid calling the API if possible, we do already
check if the given template requires a server connection, so let's
move updating the API version to that block.
