Remove trailing-whitespace (backport #5203)

[mergify]

Description

I have added the following hooks as part of the pre-commit:

• end-of-file-fixer
• mixed-line-ending
• trailing-whitespace

This prevents empty whitespace and additional newlines from registering as a separate commit during development.

Additional Information

• We can integrate codespell and sphinx-lint into the pre-commit, hence simplifying the workflow.
