CNJR-3040 Self Updating Summon Formula

Desired Outcome

The motivation for this is to the able to automatically release projects that publish to homebrew and not have to push commits to this repo for each release.

Implemented Changes

This is a homebrew formula for installing summon that doesn't have a hardcoded version - it finds the latest release from GitHub and provides that.

The versioning is maintained, so brew will know the current version that is installed and when there is an update available.

Installing old versions won't work, but that doesn't work currently either AFAICT.
