Don't generate `.mo` files
What does this MR do?
This skips generating mo files which we don't use. Generating the MO files also caused the po files to be regenerated, including the buggy fuzzy translations.
Why was this MR needed?
Otherwise we'd generate invalid po (and JSON) files while installing.
I've tried this out locally, translations seem to work fine without MO files
What are the relevant issue numbers?
