Installed module missing from API representation of module bay

[jeremystretch]

NetBox version

v3.2.5

Python version

3.8

Steps to Reproduce

1. Create a module bay
2. Install a module into the module bay
3. View the module bay using the REST API (e..g. GET /api/dcim/module-bays/123/)

Expected Behavior

The installed module should be included as installed_module, similar to installed_device for device bays.

Observed Behavior

The field has been omitted from the REST API serializer for the ModuleBay model. It's clear this was intended for the initial implementation, however the code for including the field is currently commented out, and no proper nested serializer was created. It's likely this was an oversight during the development and evaluation periods.
