[Docker] Alpine image fix (#9118)

* Revert to alpine3:20 / postgres:16

* Remove old hack

- No longer needed as we are using python 3.11

* Update package requirements for devcontainer

Also fixes some docker warnings from the alpine Dockerfile

* Specify SITE_URL

* Reduce log output during docker image testing
