1.14 release notes: "Python is Optional" Fix inaccuracy, reorder text
* docs/release-notes/1.14.html:
("Python is Optional" note box):
Fix inaccurate statement regarding hook scripts coded in Python
being (necessarily) affected by the change to Python 3. This is
only true of scripts that use the SWIG Python bindings. Also,
reorder the text for readability: immediately after mentioning the
SWIG bindings, list what they're used for.

So, the link works, but when clicking it, the yellow background is
replaced with dark grey, due to the usual logic for links to anchors[1].
Should we consider this a bug or a feature?
Personally, I find box easier to read when it isn't wearing a high-
visibility jacket, so to speak.
Cheers,
Daniel
