Improve astro-cli UX when user trying to work locally without access houston

[andriisoldatenko]

fix https://github.com/astronomer/issues/issues/1516

should work without access to houston server:

• astro dev init
• astro dev start
• astro dev kill
• astro dev logs
• astro dev stop
• astro dev ps
• astro dev run

and astro version should print correct message instead of crashing:

astro version
Astro CLI Version: 0.16.0
Git Commit:
Astro Server Version: Please authenticate to a cluster to see server version

LGTM, I assume the git commit only shows when running a local build right? Could that come first? Just seems out of order to have the git version sandwiched between the two different Astro-versions.
