In certain scenarios, the Node Editor lacks the `RGN_TYPE_ASSET_SHELF` &
`RGN_TYPE_ASSET_SHELF_HEADER` regions.
That is because the versioning code from 0a0dd4ca37 only creates these
for Node Editors that are Compositors.
That does not seem right. The thing is, if you change a non-node Editor
(e.g. an Image Editor) to a Compositor editor, all is fine (`SpaceLink
*node_create` gets called, the regions set up correctly), but changing
an **existing** node editor (e.g. Shader or Geometry Nodes) to a
Compositor, no new Space gets set up (rightfully so) and we are then
missing the regions.
I dont really see an issue with having the versioning setting up shelf
regions for **all** node editors (the shelf polls will already take care
of it only showing in the Compositor) which is what this PR does.
Now we are in the unfortunate situation that people might have saved
their `startup.blend` (or other files affected by that) in the meantime,
so versioning will not kick in anymore, so we probably have to do
another versionbump (which will happen in `main`).
