Document quirks when using TranslationServer in the Editor

[betalars]

This is a small enhancement to the TranslationServer documentation mainly aimed at preventing #98935 from being raised again in the future.

Feel free to not use the code example. I think it adds some utility and clairity, but may be better suited for a dedicated tutorial on different tool quirks I am still trying to work on in the background.

Hm, I don't seem to understand why the check failed.

TranslationServer will not load translations in the editor.

It loads.

But the main domain and godot.* domains are controled by the editor. e.g., disabling translation preview disables the main domain. So when translation preview is off, calling translate() on the main domain won't translate anything, and your MRP for #98935 still fails.

I think your sample code is too scenario specific. It could just be adding a note like:

[b]Note:[/b] The editor uses the main translation domain internally. Do not use tool scripts in the editor to perform operations involving the main translation domain unless you know what you are doing.

I'm not sure about the wording.

@timothyqiu okay I really got this backwards then trying to explain it from the responses I have gotten to my bug report.

Thanks for the fact-check, I fixed it based on your advice.
