Investigate possible problems caused by "Using Godot;" being changed to "using Redot;" in docs/translations files

[SkogiB]

Just a note for the core crew so we don't forget
4.3 and 4.4dev

[Majoramari]

We should revert it to Using godot; because the code "using Redot;" is not valid

Also, to maintain compatibility with Godot

[ActuallyTheOwner]

If anything has already changed, we should not go back on it.
A hard fork early on might prove beneficial and makes Redot distinct from Godot.

[Spartan322]

It should be using Godot, we are not intending to breaking compatibility with Godot any time soon, and with stuff like this we likely never will.
