What changed in this PR

This PR standardizes docstrings across PyMongo, BSON, GridFS, and supporting tests by enabling additional Ruff checks. Changes are limited to lint configuration, docstrings, and whitespace; executable logic is unchanged.

Changes:

• Enable Ruff rules D202, D209, D301, and D403 with the PEP 257 convention.
• Normalize docstring spacing, closing quotes, and capitalization.
• Use raw docstrings for escape sequences and correct a Sphinx version directive.
