[docs] [issue17074] (docs) Consistent formatting of constants

[Zearin]

New submission from Zearin:

When reading the docs, I noticed that the capitalization and formatting of the Python constants ``True``, ``False``, and ``None`` were inconsistent.

The attached patch contains a fix for all such occurrences under ``/Doc/library/``.

(I **think** I correctly made the patch.  I hardly ever make patches, so if I screwed up, let me know and I’ll see if I can get it right. ☺)
