This pull request fixes an assortment of typos and improves conciseness in `Animation`, `Area2D`, `Array`, `ArrayMesh`, `Control`, `Directory`, `EditorPlugin`, `Engine`, and `OS`.
Namely, move the drive dropdown to just the left of the path text box and don't include the former
in the latter.
This improves the UX on Windows.
In the UNIX case, since its concept of drives is (ab)used to provide shortcuts to useful paths, its
dropdown is kept at the original location.
We already removed it from the online docs with #35132.
Currently it can only be "Built-In Types" (Variant types) or "Core"
(everything else), which is of limited use.
We might also want to consider dropping it from `ClassDB` altogether
in Godot 4.0.

All 100% completed: MainLoop, Node, Object, Path, Performance,
Reference, Resource, SceneState, SceneTree, UndoRedo.
Also fixed some en_GB occurrences as the reference spelling is en_US.
In many of the XML files it had been noted that when the documentation
refers to a return value, both "Return" and "Returns" are used. This
has now been fixed to only say "Returns".
Fixes#28867
