convert.py, markdown: Fix right single quotation mark.

Some generated markdown have right single quotation marks, and without
this fix, it ends up being displayed as '???' in the generated HTML
files.

As an example with site/new-replicant-test-images-available.html we
have:
    We are please to remind you that, as usual, Replicant is fully
    free software and doesn???t include any proprietary firmwares.

Converting the right single quotation marks to apostrophes fixed it.
