// defaultSystemPluginDirs are the platform-specific locations to search
// for plugins in order of preference.

// Plugin-discovery is performed in the following order of preference:
//
// 1. The "cli-plugins" directory inside the CLIs config-directory (usually "~/.docker/cli-plugins").
// 2. Additional plugin directories as configured through [ConfigFile.CLIPluginsExtraDirs].
// 3. Platform-specific defaultSystemPluginDirs (as defined below).
