fix(templates): radarr/nabarr grants sonarr-only importlistexclusion endpoint

radarr/nabarr.json includes /api/v3/importlistexclusion and
/api/v3/importlistexclusion/{id}, which do not exist on Radarr — that
route name is Sonarr's ImportListExclusionController
([V3ApiController] with no route override, so it defaults to the
controller name). Radarr's own exclusions controller explicitly
overrides its route to "exclusions" ([V3ApiController("exclusions")]),
which is already correctly granted in this same file.

Confirmed via Radarr/Sonarr source (ImportListExclusionController.cs
in both repos) and via nabarr's own client (l3uddz/nabarr): the Radarr
client only ever calls GET /exclusions, the Sonarr client only ever
calls GET /importlistexclusion — never both on the same arr type.
Removing the dead Sonarr-shaped grant from the Radarr template.
