Make pre-receive-check-po refuse non-ascii quotation marks in link syntax
https://gitlab.gnome.org/GNOME/gnome-devel-docs/-/issues/20 broke the build by accidentally using “
and “
(U+201C and U+201D) instead of \"
(U+0022) for link syntax in a po file.
I wonder if https://gitlab.gnome.org/Infrastructure/sysadmin-bin/-/blob/master/git/pre-receive-check-po could catch that in some feasible and maintainable way.
If not, then please feel free to decline this ticket.
