Translations for 2.4.4

[Richard Kimberly Heck]

We are now moving towards the release of LyX 2.4.4. Please prepare 
translations by the 1st of June. I'll plan to do the release that week.

Note also that we are starting to think about the release of LyX 2.5.0. 
I will be releasing something akin to a beta version later in June, so 
you might want to start having a look at the translations for that. But 
there is certainly a lot of time still before we'll be ready for that 
release.
