Trigger Policy Service re-sync after org transfer (#15924)

The GitHub Policy Service (GitOps bot) stopped processing policies after the
repository was transferred from dotnet/aspire to microsoft/aspire. This no-op
change to a policy file triggers a webhook that should cause the Policy Service
to re-sync and start processing policies for microsoft/aspire.
