* Created new setting for jackett that allows specifying a [filter-index](https://github.com/Jackett/Jackett?tab=readme-ov-file#filter-indexers) when not set will default to `all` leaving current behavior in place.
* Updated initial migrations to include new `nefarious_settings.jackett_filter_index`
* Updated `verify_settings_jackett` to include the set `nefarious_settings.jackett_filter_index` during verification
* Updated `get_jackett_search_url` to return with the current `nefarious_settings.jackett_filter_index` used.

Issue: [Fixes Issue #292](#292)

* Installing pip 24.0 to avoid build failure see [pypa/pip#12063](pypa/pip#12063)
* FIxes Issue #294
