tsq: update parser to fix escaping double quotes

This includes a fix for the new HTML highlights introduced a few
parent commits back:

    ["\"" (attribute_name)] @string

Would get tripped up and the entire line would be highlighted as
a string. Now `\"` is a valid escape.

I'm switching to my fork as the primary repo as the upstream hasn't
been touched in over a year (mostly because stability afaict) but
it has no watchers currently so I'm not hopeful that my PR will
be merged.
