Revert "gh-36678: CI conda: Ignore baseline test failures "

[tobiasdiez]

Reverts #36678, which was marked as "positive review" although not all reviewer concern had been addressed.

I'll set this directly as "positive review" since this is a trivial git revert.

This nonsense really needs to stop.

It really doesn't work this way, even if you think that a particular PR should be reverted.

This is obviously not a blocker.

This PR is not appropriate and is a violation of Sage's code of conduct: directly reverting a PR where you disagree with the community's decision, then giving yourself positive review with a comment that it is a "trivial git revert" is completely unacceptable.
