Upstream po4a has received several updates recently that improve markdown support. Our scripts currently process .md files as asciidoc and work well enough, but this can be improved. I've been doing some tests on my repo and would like to implement these improvements in our scripts (and update the po4a .deb package in the assets repo).

These improvements are mainly about stripping out markdown formatting like # (translators don't have to worry about how many there are), ``` (identifying code blocks and treating them as such) and '-' symbols from .po files and some other things. After a .po file update there will be a lot of translated strings that will be marked as fuzzies though, but I can fix those myself.

So to do this update I would like to ask that after merging the translation updates currently on Weblate, we lock it temporarily to avoid conflicts while it gets done. I hope to have time next Monday 12 September during the morning - it should only take a couple of hours. This update should in future reduce the chances of errors made with markdown formatting and save translators from having to worry about it.
