Update all formulas repositories at once

[GuillaumeFalourd]

What would you like to be added:

The possibility to update all formulas repositories together.

Why is this needed:

Today, the rit update repo command only update one formula repository at a time. It would be interesting to have the possibility to update all repositories with one command:

➜  ~ rit update repo
? Select a repository to update:   [Use arrows to move, type to filter]
> ALL
  commons
  demo
  formulas-insights

And then select which version I want to use for each repo during the execution.

Hii @GuillaumeFalourd, I'd like to work on this issue.
Can you guide me and help me get started?
I'm new to the Go language, going through its documentation and trying to understand file: pkg/cmd/update_repo.go.
Am I going in the right direction?

Hi @Harirai

Yes, you're going in the right direction 👍

My suggestion would be for you to test the rit update repo command first, to understand how it works.
Then, think of a solution to execute it only once for all repositories contained in the list.
Moreover, it may not be necessary to ask the user to update a repo that is already with the last available version.

Start with this, and let us know if you have any question.
