Use uv for running check.py (#1040)

Use uv to run and manage the environment in which the check.py runs.

* Add the dependencies required to run the check.py script to a new
check dependency group. Note that to avoid automatically installing
these dependencies into the environment the dev group is not used.
* Update check.py to use `uv run`
* Update the check workflow to use uv.
