Example of using pylint as a pre-commit hook does not mention use of spelling extra

[ssbarnea]

Bug description

At this moment there is no documentation on how to install the spelling extra when defining the pylint pre-commit hook. Just adding a pyenchant inside additional_dependencies does risk installing a version that is not compatible with the runtime requirements from https://github.com/pylint-dev/pylint/blob/main/pyproject.toml#L56

In the doc we have a pre-commit installation guide: https://pylint.readthedocs.io/en/latest/user_guide/installation/pre-commit-integration.html#pre-commit-integration, where we suggest to use a local installation (where the install would supposedly be pip install pylint[spelling] if using pyenchant). I don't like the additional_dependencies solution because it's duplicating the dependencies between pre-commit config and the default packaging (pre-commit is never going to support editable install afair). We're going to upgrade the pre-commit doc in #9463, we could detail what to do if you feel it's necessary.
