Only one version when running storage tests (#2643)

#### Reference Issues/PRs
<!--Example: Fixes #1234. See also #3456.-->

#### What does this implement or fix?

Currently for storage tests we run all OS-Python combinations, although
storage tests are executed only with Python 3.11 on Win and Linux. That
creates a mix of results where majority 3.8-3.10, 3.12, 3.13 are LMDB
tests and only 3.11 are real storage tests. That creates lots of
confusion. The ideal solution would be to limit to 3.11 the runs so that
only results from real storage tests are in the runs. For example see
this link of a run of real_tetsts:
https://github.com/man-group/ArcticDB/actions/runs/17659474240. It has
so many LMDB runs and only 2 are Real Storages. Can you guess which
ones?

A run for GCPXML:
https://github.com/man-group/ArcticDB/actions/runs/17643448437
Note: Linux - 3.8 still exists, and that is because it uses
matrix-include which cannot be created with a condition. Still all
others are gone from the run
