[BUG] TMDB ID Not Extracted

[artifaxx]

Describe the bug
Currently Yamtrack tries to extract the tmdb_id value from the Item.ProviderIds.Tmdb field. The payload currently received from Jellyfin does not have a value in that location, but instead has it in the Series.ProviderIds.Tmdb field.

To Reproduce
Watch an episode for which there is no TMDB External ID configured.

Expected behavior
Yamtrack falls back to extracting from the Series details.

Screenshots
Trimmed down payload received in the webhook.
