Turn off doc checks on translations that are far from done

[robe]

woodie is taking a really long time on docs. Most of the time is doing check-xml.

Each check-xml run takes 5-6 minutes to run.

I'd like to turn them all off except for ja, fr, and de.

The other languages are too far from being completely translated to care about at this time.

TURN OFF check-xml except for ja, de, fr

Other languages are so far behind, it's a waste of time checking
and takes 6 minutes for each language checked

The docs.yml content after the DO NOT EDIT line is generated from .woodpecker/update-docs-localized.sh so that's where laguages should be skipped, if at all.

The conditionals should result in ONLY building the localized languages that are actually translated so it shoudln't be a huge deal to keep them all.

See ​https://git.osgeo.org/gitea/postgis/postgis/pulls/135 for how languages could be skip, if there's a compelling reason to do so
