[action] [PR:3721] [show][interface] Add changes for show interface errors command

[mssonicbld]

MSFT ADO 30169175

What I did

This pull request introduces a new subcommand to the show interfaces command, allowing users to view error statistics for network interfaces. The new errors subcommand displays a table of potential interface errors, including error types, counts, and the last timestamp (in UTC) when the error occurred. If an error has not been encountered, the count defaults to 0, and the timestamp is displayed as Never. This change helps users easily identify any issues with their network interfaces and track error occurrences.

How I did it

To implement the errors subcommand, added a new command handler to the show/interfaces/init.py file. The handler retrieves the error data for a specified interface from the PORT_OPERR_TABLE in the database. The error types are predefined in a list, and for each type, the count and timestamp are pulled from the table. The results are then formatted into a table using the tabulate library, sorted alphabetically by error type.

How to verify it
