[pycodestyle] Don't treat None, True, or False as keywords (E271-E274)

[fixfon]

pycodestyle excludes None, True and False from its keyword list (KEYWORDS = kwlist - SINGLETONS), but ruff was still flagging whitespace around them in E271-E274. E275 already handles this correctly, so I just added the same !is_singleton() check in whitespace_around_keywords.rs.

The example from the issue used to give E272, now it passes. Two existing fixture cases (True and False and True\t\tand\tFalse) now report what pycodestyle reports, so I moved them under their own #: headers and added a few new cases to E27.py.

cargo test -p ruff_linter passes and clippy is clean.

E225/E226 seem to have the same mismatch. I left that out to keep this small, happy to open a separate issue.

I used an AI assistant while working on this. I went through the change myself and checked it against pycodestyle.

Fixes #29215
