Enable pre-commit autoupdates

The current pre-commit config depends on https://github.com/astral-sh/ruff-pre-commit/releases/v0.1.8 while the newest version is https://github.com/astral-sh/ruff-pre-commit/releases/v0.2.0 ([changelog](https://github.com/astral-sh/ruff/blob/c53aae0b6f037b0d664f2d63364adbd02fb5acbc/CHANGELOG.md#020)). While we can manually update these dependencies, there is some room for automation.

Considerable options are:
- enabling https://pre-commit.ci service for this repo,
- adopting [renovate](https://github.com/renovatebot/renovate),
- waiting as long as https://github.com/dependabot/dependabot-core/issues/1524 is open [with the possibility to supply a temporary workflow](https://github.com/astral-sh/ruff/pull/8411/files).

Start by reviewing the current pre-commit configuration and comparing the pre-commit.ci, Renovate, and temporary workflow options described in the issue. Choose and document an automation approach, then verify that it updates the Ruff dependency without disrupting the repository's existing checks.
