Fixed the json err now cardDetail working fine

[Priyanshu2004-Singh]

This PR fixes invalid JSON in [cardDetails.json]
The following issues were addressed:

1. Fixed inconsistent/misspelled keys for one contributor entry:
2. "Profession" -> "profession"
3. "quota" -> "quote"

Added a missing comma between two contributor objects which caused the JSON parse error at the end of the array.
Normalized the object structure so all contributor entries use consistent key names.
Files changed

Why this change

The malformed JSON prevented consumers (frontend or ingestion scripts) from loading the contributor cards.
Normalized keys improve consistency and reduce runtime errors in code that expects specific field names like profession and quote.
