gh-36678: CI conda: Ignore baseline test failures

    
<!-- ^^^^^
Please provide a concise, informative and self-explanatory title.
Don't put issue numbers in there, do this in the PR body below.
For example, instead of "Fixes #1234" use "Introduce new method to
calculate 1+1"
-->
<!-- Describe your changes here in detail -->

<!-- Why is this change required? What problem does it solve? -->
This makes the CI conda pass by marking affected files as "known
baseline failures", thus reducing the noise that this workflow makes on
PRs (including
#36666 (comment))

Less intrusive version of #36372.

In addition to the failure marked there, here we collect a number of
more failures observed over the course of a week in
https://github.com/sagemath/sage/actions/workflows/ci-
conda.yml?query=is%3Acompleted

<!-- If this PR resolves an open issue, please link to it here. For
example "Fixes #12345". -->
<!-- If your change requires a documentation PR, please link it
appropriately. -->
