Integrate translation platform (e.g Weblate)

[juliazero]

Is your feature request related to a problem? Please describe. Translators have trouble making translations for microG, files are scattered in different places. I suggest integrating Weblate into the project and only make translations on it.

Describe the solution you'd like Integrate a translation platform (e.g., Weblate hosted or selfhosted)

Describe alternatives you've considered Another alternative is Crowdin or Transifex, but Weblate is an open source project.
