add full names for cloud providers in guided init

Fixes #1708
PR #1744 was made for this before and @iameskild had described a good solution, but the difficulties faced last time arose due to the fact that there's a pydantic root validator in place which then doesn't allow inputs.cloud_provider to store full cloud provider names outright. The feature can be implemented by simply using a new variable to hold the inputs from the user and then still passing the accepted enum vals on to inputs.cloud_provider.
It's a very very minor change!

@exitflynn local integration tests are failing but it's unrelated the changes in this PR. Once we have solved that, I'll merge it.
