fix #2463 and #2464

@codrin-ch thanks for contributing!
The WITHSCORE argument should be implemented as a separate command since it has other return type (ZRANK_WITHSCORE and ZREVRANK_WITHSCORE). See ZDIFF_WITHSCORES for example.

I think the coverage missing is due to the redis version from the testing cluster.
The tests have the min version 7.2 and as a result I suspect that the tests are skipped for the new functions

@codrin-ch this is exactly what is happening. I'll add Redis 7.2 to the tests matrix soon.

Can something be done to finish this?
