feat: Use a translation platform to simplify localization

[juliazero]

Requested feature:

I propose to integrate a translation platform. (Not for automatic translations)
This will allow people who are not familiar with github usage to translate Mainsail.

Solves the following problem:

This will eliminate problems with incorrect pull requests, and will generally speed up the translation process.

Additional information:

I'm suggesting to integrate Weblate like Spoolman, Fluidd, Klipper and KlipperScreen did.
Fluidd and KlipperScreen are waiting for approval for free hosting.
Weblate is free and open-source and can be selfhosted, but there is also alternatives like Crowdin or Transifex.

I can help with this if needed.

@Daviteusz can I ask, why you close this FR? I hadn't time until now to look closer at this tool.

[juliazero]

There was no response from almost three months, so I assumed there was no interest 😅

sorry, that was my mistake. i should have written a short comment to let you know that i need some time to have a look at this tool. unfortunately, i don't have any experience with it yet.
