I'm modifying a github workflow that uses google-github-actions/auth. After making some changes to introduce new environment variables I started getting a new warning when my action runs. From the raw logs for my action I determined that this warning is coming from the auth action, presumably from here. The warning is:

"Overwriting existing environment variable GCP_PROJECT (was: "...")"

This warning message is incomplete and not actionable, and could be improved. Some thoughts:

• What is the value that the variable is being overwritten with? I can see what it was but not what it will be.
• Who is doing the overwriting? This is really an issue with the GitHub UI (I shouldn't have to dig into the raw logs to figure this out), but until GitHub improves that the message could perhaps say "google-github-actions/auth is overwriting existing..."
• Most importantly, what should I do about it? Does it matter that the auth action is overwriting my environment variable? If it doesn't matter or there's nothing I should do about it, then it would be great to make this a debug statement instead of a warning.
