This reverts commit 169511959497bd4509305c5424532e817c6a9cb2.

In Cloud Datastore ancestor queries are intended to be strong by default
(https://cloud.google.com/datastore/docs/concepts/structuring_for_strong_consistency) .

In Cloud Firestore in Datastore mode, all queries should be strongly
consistent by default (https://cloud.google.com/datastore/docs/upgrade-to-firestore).

Fixes #666

* feat: detect obsolete BQ Storage extra at runtime

* Cover the changes with unit tests

* Skip BQ Storage version tests if extra missing

* Rename and improve _create_bqstorage_client()

The method is renamed to _ensure_bqstorage_client() and now performs
a check if BQ Storage dependency is recent enough.

* Remove BQ Storage check from dbapi.Cursor

The check is now performed in dbapi.Connection, which is sufficient.

* Remove BQ Storage check in _pandas_helpers

The methods in higher layers already do the same check before
a BQ Storage client instance is passed to
_pandas_helpers._download_table_bqstorage() helper.

* Simplify BQ Storage client factory in magics

Lean more heavily on client._ensure_bqstorage_client() to de-duplicate
logic.

* Cover missing code lines with tests

* ci(python): run lint / unit tests / docs as GH actions
