Rename editor run/pause/stop shortcuts and tooltips for consistency

[Calinou]

The new naming better suits non-game applications and is more explicit.

See godotengine/godot-proposals#5223.

looks like you missed

godot/editor/editor_run.cpp

Line 263 in 581db8b

VariantWriter::write_to_string(ED_GET_SHORTCUT("editor/stop"), shortcut);

where I believe the editor stop shortcut is taken to be the same for stopping test play when the game/app is in focus.

would a separate issue be useful?

edit: nvm, I see you already fixed it in #66441
