## Summary

Changes proposed and introduced through:
astral-sh/uv-pre-commit#1 ; are being fixed and
updated for this repo as well.

## Summary

Add a GitHub workflow for creating a new release, automatically, when a
new tag is created.

This solves #78. The code is very similar to the changes added in
astral-sh/uv-pre-commit#6

The primary difference, is that the URL points to ruff and this one
checks for if the tag starts with a `v`, but it is optional. This lets
you change ruff versions to not have a `v` in the future. Although the
`mirror.py` will need to be updated.
Speaking of updates to `mirror.py`, I ran `ruff` on it and updated the
`subprocess` to raise an error on failure.

## Test Plan

Locally tested.
