Support changing the remote url

[dploeger]

Use Case

We switched our git provider and need to update the origin remote URL.

Describe the Solution You Would Like

The new URL can simply be specified in the module parameters and the origin is changed.

Describe Alternatives You've Considered

Manually changing the URL, which is quite a lot of hassle.

Additional Context

If I change the URL in the current version, I get the error: Path (...) exists and is not the desired repository.
