Is there a way to use Ruff version from PATH?

Hi,

currently we setup our pre-commit specifying a revision for Ruff.
```yaml
repos:
- repo: https://github.com/astral-sh/ruff-pre-commit
# Ruff version.
rev: v0.8.0
hooks:
# Run the linter.
- id: ruff
# Run the formatter.
- id: ruff-format
```

This installs Ruff with version 0.8.0 and works very well. However, every time we upgrade our dependencies, we have to maintain different places where the Ruff version is defined.
We would like for pre-commit to use Ruff as-is found via PATH (either installed via Shell, or if installed in an isolated venv like with `uv tool install`).

Start with the pre-commit configuration and the ruff and ruff-format hook entries shown in the issue, then investigate how those hooks resolve Ruff when it is installed on PATH. Done means both hooks can use the PATH-installed Ruff while preserving the existing version-pinned behavior.
