Add ore_algebra optional package

[sagetrac-tmonteil]

This package was removed because there was no upstream release (see #26332), but the development is still ongoing https://github.com/mkauers/ore_algebra and the developers follow the Sage development.

We should be able to use a "pip" package source type, with a requirements.txt pointing to a commit (or a tag) of the version that works with the given Sage release.

See the task #31164.

As setup.py is using sage.env, this will need a dependencies file, see discussion in #31224
