Google Team Member ba5b80d5d7 feat: use bigquery scope by default in bigquery credentials.
Right now the agent builder has to specify the bigquery scope explicitly for bigquery tools, which is somewhat unnecessary. With this change the user does not have to specify scopes, although they would still have the ability to overrides scopes if necessary.
