This will work around such errors from the g-ir-doc build:
> devel-docs/g-ir-docs/pages/python/Gimp-3.0/Gimp.checks_get_colors.page:46: parser error : EntityRef: expecting ';'
> gimp_checks_get_colors (gimp_check_type (), &color1, &color2);
> ^
Similar to commit 7123b6c466, it cannot really be considered a proper
fix, barely a workaround for g-ir-doc-tool not even able to produce
valid XML. Here we have ampersands which it should have espaced into XML
entities.
Anyway this will do for now (until we just decide to drop the g-ir-docs
tools?).
To work around the issue, I just wrote a stupid sed script. Of course,
it means that if we encounter again the issue on some other docs, we'll
have to update it. In other words, it's neither robust nor a proper
long-term fix. Just a temporary hack.

Also fixing this issue, I encountered another bug, this time in meson,
which changes backslashes in slashes on 'command' arguments, in a
completely uninvited manner! The only workaround to this is apparently
to call an external script, which is ridiculous for such a basic stuff.
But well… here is why I implement this with a script, instead of
directly calling sed in the meson 'command'.
