fix(codecommit): use region given in fromRepositoryArn when creating …

…clone urls (#10639)

As a CDK User I expect Repository.fromRepositoryArn to use the region
given when building the repository clone urls.

Prior to this commit, a stack deploy in us-east-1, would return clone
urls for us-east-1 even if given an ARN for us-west-2.

Fixes #10630
