Add rit publish repo core command

[GuillaumeFalourd]

What would you like to be added:

• There is a formula to publish new repo releases on the ritchie-formulas repository.

Note: This formula has been developed in shell and batch and has support for Github and Gitlab, only for user repositories.

Why is this needed:

• As this formula could be useful for all Ritchie users, it could be interesting to turn it a core command, with support for Github, Gitlab and Bitbucket.

Note: This means the formula would need to migrate to the Golang language, adding support for Bitbucket, as well as for organisations repositories (not only users).

Suggestion:

This core command could be developed for each git tool separately following the same pattern (if one day users ask for other tools support):

• Github

• Gitlab

• Bitbucket
