local.yaml is only loaded in the local environment, and will not be used in
production. To avoid specifying it in both production and local configurations,
use it as a default specified in the code instead (that's the pattern we're
using in other places too from what I remember, maybe we should refactor that
too, but that's a bigger task not tied to this change).
**Tested by**
On a local dev cluster
- Not specifying anything and ensuring that the default is picked
- Specifying an override in museum.yaml and verifying that is used instead
## Description
## Tests
Ran locally with the config in local.yaml and verified that it's
modified as well when I had put localhost:3002 in the museum.yaml config
