flask-redis: dev envs support & misc improvements (#265)
(Most of this is almost identical to #263.) * Docker Desktop Development Environments config * Use cache volumes for pip * Downgrade from Python 3.11 _alpha_ -> Python 3.10 * Use port `8000` to avoid conflicts with Airplay on macOS for default Flask port `5000` * Use `SIGINT` to gracefully stop Flask * Formatting fixes in `compose.yaml` Signed-off-by: Milas Bowman <milas.bowman@docker.com>pull/55/merge
