Batch Rename support for Node Groups

Not according to my testing. As mentioned in my original suggestion, it seems to be intended for use in the Node Editor, not the Outliner. When selecting from the Outliner, it won't even allow me to select Nodes as an option, whereas that option does work when selecting nodes in the Node Editor

I came through this exact same frustration an it turns out that the Batch Rename is context sensitive. Which means it will only allow the Type to be selected if you are in the correct context which in this case would be the Shader, Geometry Nodes, Compositor Editor... the "Node Editors Context".

Already here we can see at least 2 issues:

1. Outliner should be The King of the contexts for the Batch Renaming since it allow us to manage manually everything in terms of data block naming.
2. And when the context is wrong, those Type options should be displayed greyed out with a tooltip on hover telling you why is that (because atm there is no clue!)

And let's say you are in the correct context it won't either work as you expect because this 'Nodes' are meant to rename the name of the nodes that we almost don't care about.

So, that means Batch Rename lacks the ability to rename the name of the Node Group Trees indeed.
