Delete projects angular

[maddiedierker]

Note: Change base back to staging before merging!

Follow-up for #27930

Nothing uses the /projects/angular route anymore, so I'm removing it!

Great cleanup Maddie!

I'm not sure what all you are planning to tackle at this stage, but here is one instance that can be removed:

• code-dot-org/dashboard/app/assets/stylesheets/application.scss

  Line 1558 in daa5056

  #angular-my-projects-wrapper .gallery {

And here's one that might warrant follow-up. perhaps you have a better sense of the priority of doing so than I do:

• code-dot-org/apps/src/lib/ui/SyncOmniAuthSectionControl.jsx

  Lines 66 to 68 in 1cad5ac

  	// While we are embedded in an angular page, reloading is the easiest
  	// way to pick up roster changes. Once everything is React maybe we
  	// won't need to do this.
