chore: few tweaks on linters and Cargo (#814)

* chore(ruff): fully rely on `requires-python`

As mentioned in https://docs.astral.sh/ruff/settings/#target-version,
Ruff can read `requires-python` to determine the minimum Python version.
This is one less reference to upgrade when we drop support for a Python
version.

* chore(cargo): depend on exact versions

* chore(mypy): remove obsolete `show_error_codes`

It is already enabled by default.

* chore(ruff): remove `E731` ignore
