Do we have a separate issue open for NumPy 1.x? According to https://endoflife.date/numpy, only NumPy 2+ is currently supported upstream. Removing our support for NumPy 1.x could simplify some things quite a bit.

We have one:
I am going to mark all those issues as 26.0.0 to see if we can track them to bump all of them.

Pull request overview
Drops Python 3.10 support across PyArrow packaging, documentation, CI, and release verification tooling in preparation for the 26.0.0 release, aligning the repository’s minimum supported Python version to 3.11.
Changes:
- Bumped minimum supported Python version to 3.11 (packaging metadata, Archery tooling, docs, and helper scripts).
- Updated CI/Crossbow/Archery configurations and Docker images to stop using Python 3.10 and to use newer baseline images where needed.
- Updated release verification scripts (shell + Windows batch) and tasks definitions to remove Python 3.10 wheel/sdist testing.

Rationale for this change
Python 3.10 is End of Support on October 2026. We can drop support on PyArrow 26.0.0.
See: https://endoflife.date/python
What changes are included in this PR?
Remove support for 3.10. Update minimum required Python version and update some CI jobs to use the minimum Python supported version.
Some CI jobs using default Python 3.10 (Ubuntu 20.04) have been bumped.
Are these changes tested?
They will be tested via CI and Archery
Are there any user-facing changes?
Yes in terms of not supporting older versions of Python. This will be a breaking change for some users but not for the API itself
