Use uv-pre-commit to validate lockfile

[danielhollas]

The previous uv hook that checked whether uv lockfile is up-to-date required the developer to have uv installed. Using the official uv-pre-commit hook, this is no longer the case. The hook also updates the lock automatically, instead of just checking its status.

Here's the output that I got when I bumped the mypy package in pyproject.toml

❯ pre-commit run uv-lock --all
uv-lock..................................................................Failed
- hook id: uv-lock
- files were modified by this hook

warning: `VIRTUAL_ENV=/home/hollas/.cache/pre-commit/repovyb9qrvk/py_env-python3.12` does not match the project environment path `.venv` and will be ignored
Resolved 263 packages in 2.50s
Updated mypy v1.13.0 -> v1.14.1

(the warning is a bit unfortunate interaction between uv and pre-commit, I opened astral-sh/uv-pre-commit#36 and asked if it could be hidden so that it is not confusing for devs)

I think it's better to have this check only in one place.

Hmm, this might be a problem, looks like pre-commit.ci blocks network requests. I think I've read about this in uv issue tracked

Using CPython 3.10.12 interpreter at: /usr/bin/python3

EDIT: Indeed, this is a known issue when using dynamic metadata (such as version in our case) in `pyproject.toml: astral-sh/uv-pre-commit#35

This might get resolved in next uv version: astral-sh/uv#10622
