feat: move electron to peer dependency (#3046)

move electron to a peer dependency, this is not a breaking change as projects implementing electron applications specify the version of electron that they use as a devDependency by convention. The version range allowed is very wide and covers the old version that we were using up to the current version of electron.

fix: make scope aware requests work for electron apps
  adds support for passing approved scopes to front end via context bridge
