Github integration: create a branch does not push new branch to GH

[flovntp]

On a PSH project, if [GitHub|GitLab|Bitcuket] integration is enabled, when creating a new branch using platform branch <new-branch>, it does not push the new-branch to Git repo.
This means the CLI process creates the PSH environment but right after finishing, the integration process deactivates and deletes the new env (as the branch does not exist on Git repo side).

It could be great to warn PSH CLI users that this branch needs to be pushed using Git CLI (git push) or make the PSH CLI to push the branch to Git repo.
