[pre-commit] Require pre-commit v4.5.1

In December 2025, pre-commit v4.5.1 was released.  We currently require v3.2.0
(released in March 2023), or later.

It occurred to me that allowing such a large range of releases might lead to
developers experiencing different behaviors, perhaps running into bugs that
are already fixed in later releases.

Fix this by requiring the latest release, v4.5.1.

The drawback is that we now require a more recent python: v3.10.

[ In more detail, pre-commit requires:
- at v3.2.0, python 3.8
- since v3.6.0, python 3.9
- since v4.4.0, python 3.10. ]

Tested on x86_64-linux, python 3.13.11 by doing "pre-commit run --all-files".
