docs: extensions: don't use utf-8 syntax for descriptions

None of the descriptions at the Sphinx extensions are using
non-ascii characters, so no need to place them under u"""
notation.

Also, according with:
	https://docs.python.org/3/deprecations/pending-removal-in-3.16.html

the 'u' format code is scheduled to be removed in Python 3.16.

So, let's just use """.
