ci: remove check_todos.yml.

Replace the functionality provided in `check_todos.yml` with the
`pre_commit_checks.yml` workflow, by adding 'TD' to the ruff rule
selections, and ignoring 'TD002', in the `pyproject.toml`.

This has the additional benefit of informing users of the CI
expectations in pre-commit.
