allow the user to choose the branch/release of the plugin repository

Based on our earlier discussion, it was suggested to incorporate a new feature into upgrade command #43.

Specifically, the proposed idea involves the addition of an option to select a specific branch or release of a remote repository, which can be specified by passing a flag. An example of the syntax for using this feature would be
coffee upgrade folgore --release 2.1

It is important to note that this proposal assumes the presence of only one plugin in each remote repository.

I think such feature would improve the overall user experience.

I agree, we should start experimenting with it, I will move this as an issue :)
