Request individual seasons from Jellyseerr (#1060)

## Description
Adds a dialog to select individual seasons for a TV show when requesting
it via Discover/Jellyseerr

If a request is already pending, it can be updated. If there's more than
7 seasons, a second submit button is added at the bottom of the dialog
for easier access.

Also, adds a button from Jellyfin series details to its Discover
equivalent and added a request button for partially available series to
request more seasons.

### Related issues
Closes #961

### Testing
Emulator & Jellyseerr 2.7.3
