Fix flaky mongo provider tests: disable testcontainers ryuk reaper in CI
(#67882)
On long provider / Airflow-compat test runs the session-scoped MongoDB
testcontainer was being reaped by testcontainers' ryuk before the mongo
hook tests ran, causing a cascade of 'Connection refused' errors at the
setup of every TestMongoHook test (container started fine early in the
session, then vanished by the time the mongo module executed — the dumped
container logs were empty because it was already gone).
The fixture stops the container explicitly in its finally block and CI
runners are ephemeral, so ryuk's auto-reaping is unnecessary and harmful
there. Disable it via TESTCONTAINERS_RYUK_DISABLED before any
MongoDbContainer is created — but only in CI, so local runs keep ryuk to
clean up containers left by an interrupted test run.
