What does this do?

On the equipment-categories route, one can now filter weapons by weapon properties.

Manually tested various http requests for equipment-categories on Postman successfully. Followed swagger README instructions to set up local development environment which ran successfully after adding new openapi documentation.

Is there a Github issue this is resolving?

Yes, this resolves issue #232

Was any impacted documentation updated to reflect this change?

Yes, I updated the swagger documentation according to the guidelines found in the swagger README.

@ThomasGCarpenter Can you look into why your tests are failing?

Sorry. I think I misunderstood what this PR was trying to do. You're altering the /api/equipment_category/${index} route to filter the weapons that are returned with it by property? You could maybe do something with /api/equipment route that would make a bit more sense. Alternatively, you can easily do this query with the GraphQL endpoint.
