The `cockroachdb` PyPI package (last released 2021) is abandoned, and its
SQLAlchemy dialect references sqlalchemy.dialects.postgresql.psycopg2's
PGCompiler_psycopg2, which SQLAlchemy 2.0 removed. Constructing a
cockroachdb:// engine has raised ImportError since the SQLAlchemy 2.0 bump
(#42803) landed, with nothing catching it: the driver isn't part of the
default dev/CI install, and the existing test_crdb.py only exercises
convert_dttm(), never a real engine.
Switches the `cockroachdb` extra to sqlalchemy-cockroachdb, the actively
maintained replacement already linked from CockroachDbEngineSpec's own
docs_url, adds it to the default dev install so this keeps getting
exercised, and adds a regression test that constructs a real engine
(verified to fail against the old package, pass against the new one).
