The joinlemmy one is here: https://weblate.yerbamate.ml/projects/lemmy/joinlemmy/bg/

The lemmy one has been requested (i'll add it here if it gets approved).

If I have any fellow countrymen on here - help is appreciated, so we could help bring more people on board. At a later point I might consider hosting a localized instance.

Edit: here's the link to the main lemmy site translation: https://weblate.yerbamate.ml/projects/lemmy/lemmy/bg/
