Revisit whether GH actions belong in the Template Selection

[ryestew]

Describe the bug
The GH Actions are now very buried deep into the Template Explorer. Before they were in the hamburger menu. Now unless you know they exist and know where they are, you'd never find them. While they may have limited fan base, they don't deserve to be so hidden.

Also these scripts are part of the the Workspace Templates Explorer - that is accessed by clicking a menu item that says Create Using Template. But if I'm looking to add a script to a Workspace, I'd need to know that both:

1. I can add files to a Workspace in addition to creating a new workspace.
2. That these templates contain templates that only contain a script.

So it seems if we are pushing a script, there should be a more direct way of labelling (by returning it to the hamburger) or adding a filter for it (probably a generic script filter won't do the trick).

But if we want to add this filter, then color coding of the filters should be abandonned because we'll be beyond the 7 or so colors that can be differentiated by most humans.
