## 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
https://github.com/astral-sh/uv-pre-commit/pull/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.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
- `pre-commit-mirror-maker` is not suitable for generating multiple
hooks in single `.pre-commit-hooks.yaml` file.
- So replaced the script and github workflows.
## Test Plan
<!-- How was it tested? -->
- Update `pyproject.toml`'s `ruff==0.0.290` into `ruff==0.0.289`, and
run the script.
```sh
$ python3 mirror.py
...
```
