Setup Wizard: Feedback about local setup wizard UI and status

Feedback from @slimsag

• I was surprised to see you can’t select multiple Git directories, only ‘one folder containing them all’
• Under Remote Repositories, if you select GitHub it just demands an access token & doesn’t tell you where to get one, what scope/permissions it needs, or if it needs to be an old or new style access token, etc.
• It always seems to say “Indexing…” at the bottom of the screen. Note that App doesn’t have Zoekt/ search indexing, so I don’t think it will ever report as “finished indexing”?
