test: upgrading the ci/cd pipeline to reduce turnover time.

Fixes #778 🦕

QUESTION / BLOCKER:

Thanks for making ci/cd more efficient! Just to double check, are we getting rid of pre-release tests altogether? Also owlbot added something. I'm not sure if this came from some new internal change, or we need to change owlbot.py.

There were two versions of prerelease testing.

• prerelease (this one is intended to remain)
• prerelease-deps (this was basically a duplicate AND it never runs (because it is not part of the google3 configuration setup) so I attempted to delete it.

Also owlbot added something. I'm not sure if this came from some new internal change, or we need to change owlbot.py.

I looked at the owlbot commit.

• It added back in the prerelease-deps file that I deleted. I will go fix that.
• AND it cleaned up a line spacing issue.
