I might have missed some discussion, but is there any reason we are switching all repositories to v1, instead of just merging v1 to main of the repository with the workflows?

https://github.com/qiboteam/workflows/issues/12

Moreover: as soon as the switch will be completed, I will change default branch in the workflows repo. At that point, main will be deprecated, and at some point even removed.
