Fix Season localization case to include number placeholder

[arnnalddo]

The season case in MetadataResult.swift was mapping to "{Season}", missing the number placeholder #. This caused the UI to display incomplete localized strings for season numbers.

This updates the mapping to "{Season #}" for consistency with the MP42Foundation fix.

Depends on: SublerApp/MP42Foundation#3

See attached screenshots for the issue before the fix:

But it's correctly translated in the Italian localisation, so while I guess it should include a #, I don't see how it affects the localisation. Plus changing that key will break existing settings.

I noticed this while working on the Brazilian Portuguese translation and updating Latin American Spanish on Transifex. I saw that several strings were missing, so I figured one of those removed translations might have caused the issue with missing localizations in the UI. On my end, updating the mapping fixed the preview.

I didn’t edit the localization files directly since you mentioned translations should only be done via Transifex, which is why I looked into modifying the code mapping instead.
