CI job to autodetect releases and make them available via brew

[cburgdorf]

This does:

1. Get rid of the brew audit warning regarding redundant usage of version (even though, I think it is wrong and leads to uglier workarounds)

2. Created a CI job that does:

• Check for new Fe releases every 10 minutes (simplest thing to do, no need for changes in the main Fe repo)
• Archive old Formulae (e.g. current fe.rb would become [email protected] and available via brew install [email protected])
• Update current Formulae to latest release and automatically create and push the commit for it

GitHub thinks this was merged because of my ridiculous way of testing it on the main branch (force pushing like a dictator) so I had to open a new PR for you to look at #7
