fix!: Fix the resource annotations for GetRepositoryRequest (#88)

* fix!: Fix the resource annotations for GetRepositoryRequest

BREAKING CHANGE: This will be a breaking change for languages that generate client libraries using resource annotations to provide overloads accepting resource names. Where previously such languages would have generated (in-pseudocode) GetRepository(LocationName) they will now (correctly) generate GetRepository(RepositoryName). Code using the older methods will be broken by this change, but would never have worked anyway.
