Making Support Curve in OpenGov Tracks more strict (#361)

## Description
<!-- Describe what change this PR is implementing -->
This PR introduces the following:
- Makes _Support Curve_ for OpenGov Tracks more strict to pass except
the `Whitelisted Caller` Track that will be used for delivering hotfixes
and new features
- Removes unused `FellowshipAdmin` origin and `fellowship_admin` track
as we don't use it for updating members of our Technical Committee


Below you can see the screenshots of Tracks with changed _Support
Curves_:
