Issue #, if available:

Description of changes:
Noted that storage plugin was requesting foreground service permission. This is a leftover from Amplify V1 and is unused - there is no Service (or foreground Service) used in Storage V2, we use Work Manager instead.

Listing permissions you don't actually use is bad form, so I've removed it.
