2023-02-07 pgadmin4 - old-menu branch

1. Adds pgAdmin4:

	- service definition
	- menu definition
	- documentation stub points to master branch

2. Consequential changes to PostgreSQL container:

	- Simplified `.env` substitution keys (environment file) so left
hand side (actual environment variable) equals right hand side (`.env`
substitution keys).
	- Adds `TZ`.
	- Added volume path for backup folder to support IOTstackBackup.
	- Reduced documentation to stub pointing to master branch.
