Failed to create repo in ADO of it already exists

When using the Azure DevOps generator and specifying the package name the same as the ADO project name, creating the new repo to push to fails.

When this happens, the following options should be made available:
- if it's an empty repo (no commits on default branch), then skip creation and push to that repo
- if it's not empty, ask the user for a new repo name

A further question here could be to always ask for a repo name and valid it doesn't exist when questioning.
