Subject: [PATCH] Expand `google-api-core pin` to `>1, <3`

To avoid diamond dependency conflicts with Cloud libraries, the Ads library should keep a `>1, <3` pin on google-api-core until https://github.com/googleapis/google-cloud-python/issues/10566 is closed.

See discussion in [doc](https://docs.google.com/document/d/1euAvUsia_4zf98lNvpwA3K0o2b4y5Xr9xAkyzCnIMzQ/edit#).
