Docs somtimes call them “main screens” and sometimes “workspaces”

**Your Godot version:**
N/A (I’m looking at [the latest revision (`aadcb081`) of the online docs](https://docs.godotengine.org/en/latest/))

**Issue description:**
[“First look at Godot's editor” talks about the 2D, 3D, Script and AssetLib main screens.](https://docs.godotengine.org/en/latest/getting_started/introduction/first_look_at_the_editor.html#the-four-main-screens) [The documentation writing guidelines say that they’re called workspaces, not main screens.](https://docs.godotengine.org/en/latest/community/contributing/docs_writing_guidelines.html?highlight=workspace#common-vocabulary-to-use-in-godot-s-documentation) Either one is fine, but the documentation should pick one and stick with it. Personally, I prefer the term “workspace” since they don’t fill the entire window (the docks, bottom panel, playtest buttons and main menus don’t disappear when switching workspaces/main screens). Also, “screen” and “main screen” could easily be mistaken for “scene” and “main scene” (I literally typed the wrong one while writing this sentence).
