When I added a new document that wasn't checked into GitHub yet, the doc
build failed with an unhanded exception:
Extension error (last_updated):
(exception: time data '' does not match format '%Y-%m-%d')
Problem is the git query looking up the last commit date for a file
returns an empty string for the date if the file exists but it's not in
the git repo (yet). The subsequent call to strptime raises an exception if passed
an empty string. This patch handles the exception.

Remove the proof-of-concept shell script that post-processes the
generated HTML to add the git date when the corresponding .rst file as
the last modified date, augmenting the existing published date.
Instead, use a custom last_updated.py Sphinx extension that's integrated
into the Sphinx build itself. Remove the old fix-git-modified-date.sh
script and calls to it.
