Revert "Temporarily redirect FIPS cloude2e tests to prod"

[ycombinator]

Reverts #5536

I was able to successfully create a 9.2.0-SNAPSHOT deployment in the GovCloud Staging region so I'm putting up this PR to direct FIPS integration tests back to that environment. Let's make sure it passes CI a few times (at least 3?) before we merge it.

This pull request does not have a backport label. Could you fix it @ycombinator? 🙏
To fixup this pull request, you need to add the backport labels for the needed
branches, such as:

• backport-./d./d is the label to automatically backport to the 8./d branch. /d is the digit
• backport-active-all is the label that automatically backports to all active branches.
• backport-active-8 is the label that automatically backports to all active minor branches for the 8 major.
• backport-active-9 is the label that automatically backports to all active minor branches for the 9 major.
