Inconsistent `RPUSH`: Command returns OK instead of Integer(length of list)

[Aditya-Chowdhary]

Steps to reproduce

127.0.0.1:7379> RPUSH mylist 1000 2000

Expected output

The expected output when the above set of commands (maybe when run on Redis)

127.0.0.1:6379> RPUSH mylist 1000 2000
(integer) 2

Observed output

The observed output when the above set of commands when run on DiceDB

127.0.0.1:7379> RPUSH mylist 1000 2000
OK

Expectations for resolution

This issue will be considered resolved when the following things are done

1. changes in the dice code to meet the expected behavior
2. addition of relevant test case to ensure we catch the regression

You can find the tests under the integration_tests directory of the dice repository and the steps to run are in the README file. Refer to the following links to set up DiceDB and Redis 7.2.5 locally

• setup DiceDB locally
• setup Redis 7.2.5 locally
• setup DiceDB CLI

Wasn't sure if I should include this in #933, so I have created a new issue for RPUSH separately.

Can I pick this up?
