[Suggestion] Use Weblate for localization

[AC19970]

I am willing to assist with the translations. While I could submit a PR, that isn't convenient. Weblate is free for FOSS projects and easy to use.

Thanks for the suggestion. The thing is Spectre's UI strings are currently hardcoded in the code, not in resource files, so there's nothing to translate yet. Externalizing them all into strings.xml is a sizable refactor I would need to do first then Weblate makes sense. I'll keep the issue open but honestly it's low priority right now.
