chore: improve output for plugin subcommand

[abangser]

Example new output:

$ ./bin/kratix plugin list
The following compatible plugins are available:

kratix local show promise                (/Users/abbybangser/dev/syntasso/home-scripts)
kratix local show schedule               (/Users/abbybangser/dev/syntasso/home-scripts)
kratix test                              (/Users/abbybangser/dev/syntasso/.kratix/plugins)
