In  [Private Service Connect](https://cloud.google.com/vpc/docs/private-service-connect), users can use an endpoint which is private to their VPC network. The request is eventually routed to the oauth2.googleapis.com/token so the "aud" in the assertion still should be oauth2.googleapis.com/token. 

After this change, service account can send requests to the private endpoint (if configured) and still use the oauth2.googleapis.com/token in the assertion.

…endpoint (#784)" (#808)

revert "feat: service account is able to use a private token endpoint (#784)" until b/194191737 is fixed.

This reverts commit 0e264092e35ac02ad68d5d91424ecba5397daa41.
