feat: Add main categories for tracker NorBits

NorBits also has these main categories in addition to the already configured sub-categories. This PR adds these main categories.

Prowlarr often return 0 query results even when there are query results, this is probably caused by all the results only having a main category (for instance "TV") and no sub-categories.

`|Warn|NorBits|Invalid Release: '<redacted>' from indexer: NorBits. No categories provided.`
