[WIP] Translation of strings starter

[Felienne]

Work in progress for the simplest first step in #4656, translating a plain text string from one language to the other. I will make a list of steps here that I have taken, and a list of things that remain to be done.

How does current, keyword translation work?
Translation now work by analyzing the parse tree, adding nodes that need translation (currently only keywords) and then replaces these keywords with simple string replacement. If you need more details, @boryanagoncharenko (who is also in Discord) created this and can help you out.

Steps taken in this PR

Hi @rania74!

I have made a small starter for that that translates code! I will add some more details but you can start exploring this PR.

This PR is a starter for @rania74, so it should stay open!

Hi people reading along (most likely @rania74)

I have made this PR a bit more extensive, now calling Google translate, and translating content inside of ASK.
