[zhumin8]

Onboard google/cloud/backupdr/v1beta API (google-cloud-backupdr-v1beta).

PiperOrigin-RevId: 981092309

Manual Touches & Configuration Overrides

• Manual configuration in librarian.yaml:
  Manually added ruby.ruby_cloud_opts overrides under the google-cloud-backupdr-v1beta entry in librarian.yaml:

  ruby:
    ruby_cloud_opts:
      ruby-cloud-namespace-override: Backupdr=BackupDR
      ruby-cloud-path-override: backup_dr=backupdr

  Rationale: Required to match the established Google::Cloud::BackupDR module namespace and non-underscored backupdr file path conventions from google-cloud-backupdr-v1 and google-cloud-backupdr (per b/561461207 #comment9).
