docs(database): setup local development guide on macOS
Context
The Container Registry can be configured to use a database to hold metadata about container repositories stored in the registry. A guide to setup a local development environment with the metadata database enabled is needed to help developers get started working on features/fix bugs related to the database.
Problem
As stated in this comment, there is currently no documented guide to setup a local development environment with the database being enabled.
Solution
Document how to setup a local development environment with the database enabled. We should have at least two guides:
- On Linux
- On MacOS
