[PATCH 1/3] Documentation: fix warnings during config build

[Ahmad Fatoum]

js_splitter_code contains backslashes that are meant for Javascript and
not for Python triggering a warning:

  conf.py:275: SyntaxWarning: invalid escape sequence '\p'
    .split(/[^\p{Letter}\p{Number}_\p{Emoji_Presentation}\-\.]+/gu)

Setting soruce_suffix to a string also seems deprecated:

  Converting `source_suffix = '.rst'` to
    `source_suffix = {'.rst': 'restructuredtext'}`.
