Describe the bug

Using the Pull Request generator with Bitbucket Cloud results in the error

error listing repos: error unmarshalling json to type '[]BitbucketCloudPullRequest': json: cannot unmarshal object into Go struct field BitbucketCloudPullRequest.author of type string

It looks like the error can be traced to adding the author field with the wrong type in [1]: it was added as a string but in the Bitbucket Cloud API it's an object [2]

To Reproduce

Create an ApplicationSet with the Pull Request generator:

spec:
  generators:
    - pullRequest:
        bitbucket:
          basicAuth:
            passwordRef:
              key: password
              secretName: argocd-controller-secret
            username: Srv-CICD-Robot
          owner: REDACTED
          repo: REDACTED
        filters:
          - branchMatch: .*/.*REDACTED.*/.*
        requeueAfterSeconds: 60

Expected behavior

The PR generator can parse the Bitbucket API response, where the author field is an object and not a string.
