Hotfix wrong formatting of docstrings with blockquote tips

[albertvillanova]

Fix wrong formatting done by make precommit on docstrings containing blockquote tips (e.g. > [!WARNING]):

• Ignore docstyle in docstrings with blockquote tips

Currently, make precommit executes doc-builder style --max_len 119 and this converts

"""
> [!WARNING]
> This is my warning message.
"""

to

"""
> [!WARNING] > This is my warning message.
"""

I have proposed a fix for hf-doc-builder:

• Fix style command for blockquote tips doc-builder#645

In the meantime, consider this PR as a hotfix that we should revert once the upstream issue is fixed.

This PR primarily adds # docstyle-ignore comments to the docstrings containing blcokquote tips. This ensures that documentation style checkers will skip these docstrings until the issue is fixed in doc-builder.
