Test numpy 2 on CI

[user202729]

As in the title. Temporary workaround.

I guess the current method is rather suboptimal (first numpy 1.26 and fpylll is downloaded, then it is discarded), but better than it not being tested.
A better way may be to generate separate yml files.

Let's see if it works.

📝 Checklist

• The title is concise and informative.
• The description explains in detail what this PR is about.
• I have linked a relevant issue or discussion.
• I have created tests covering the changes.
• I have updated the documentation and checked the documentation preview.

⌛ Dependencies

• Simplify ci-conda-yml workflow file #39240 for cleaner organization of the yml workflow file
• Make tests compatible with numpy 2.1 #39242 to fix many tests

[user202729]

this particular job has the numpy 2 test at https://github.com/sagemath/sage/actions/runs/12572088860/job/35043683578?pr=39241

Testing locally there's a bunch of failing tests because of e.g. #39242

I guess this PR wouldn't be necessary when numpy 2 is supported by official conda anyway. Just a test.

It's a great way to test the changes that are necessary for numpy 2 support. Speaking of, could you please create a new PR for the fix to flint? Thanks!
