* 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

+#### Bypassing Backup Procedure
+
+If you are connecting the docker container to a postgresql database newer than version `{{ config.extra.docker_postgres_version }}`, the [backup and restore commands](../start/backup.md) will fail due to a version mismatch. To bypass this issue when performing the `invoke update` command, add the `--skip-backup` flag.
