Merged card command with catalog. #1264 (#1285)

* remove card command

* remove unused class

* add ModelCard class

* add new card flag and update catalog function

* de-register card function in cmd.py

* remove card.py

* Refactor '--card' to a flag and add 'model' as a positional argument

- Changed the '--card' option to a flag with a default value of 'False'.
- Added 'model' as a positional argument to the 'catalog' command and made it optional.
- Implemented logic to handle the case where 'card' is provided without a 'model'.
- Added error handling to notify user if no metadata is found for the specified model when using the 'card' flag.

* Removed dead code and unncessary comments

* Fix omission by displaying errors in red

* update --card option help text
