[BUG] Tests lagging with testing only on 3.12

[maresb]

Describe the bug

I don't have bandwidth at the moment to follow up with a PR on this, but I wanted to point out that while Python 3.14 was just released, grayskull is only testing up to Python 3.12:

https://github.com/conda/grayskull/blob/ba0873b6df3aea6e7edb059074392b0c47e2e33a/.github/workflows/tests.yml#L22

Note that CRM depends on conda which isn't available yet with Python 3.14: https://github.com/conda-forge/grayskull-feedstock/pull/105#discussion_r2422985816, but hopefully that will be sorted in a few days.

Thanks @bollwyvl for pointing this out.
