Read the [project.optional-dependencies] and [dependency-groups] …

…tables (#66)

I'd quite like to use `ruff-action`'s auto-detection feature, but it
currently doesn't read the `[project.optional-dependency]` table, and
support for the PEP 735 `[dependency-groups]` table is currently limited
to only the special-cased `dev` key, and does not account for the
possibility of `{include-group="..."}` inline tables, as [described by
the PEP](https://peps.python.org/pep-0735/#dependency-group-include).

I have guessed how to make the tests work, as the only JS development I
do is plain JS (sans frameworks), so TypeScript is still quite new to me
-- feel free to push required changes to this branch.
