Bump testcontainers>=4.15.0 (#4137)

* Community modules were moved to the `testcontainers.community`
  subpackage since 4.15.0. Old imports emit warnings:
  > testcontainers.postgres is deprecated, use
  > testcontainers.community.postgres instead
* Deprecated `wait_container_is_ready` decorator is not used by
  the postgres module since 4.14.0, making the warning filter redundant
