feat: Display air date for unaired episodes

[KarpachMarko]

This pull request enhances the user experience by displaying the air date for upcoming episodes.

Changes:

• Displays Air Date: For episodes with a future air date, the component now displays "Airs on [date]".
• Placement: The air date is positioned above the episode description, which is often empty for unaired episodes.
• Styling: The air date text is styled to be slightly smaller and uses a muted color to differentiate it from other information.

How to Test:

1. Navigate to a TV show that has upcoming episodes.
2. View the list of episodes for a season that has not yet fully aired.
3. Confirm that episodes with a future air date now display the "Airs on..." text above the description.
4. Verify that the text is styled correctly (smaller, muted color).

Also it can make sense to hide rating for unaired episodes
