Describe the problem

The documentation states that we support all Redis commands. This is not correct, we support a subset of Redis commands. This caused confusion for this user (refer to intercom link).

There's also a discussion regarding new commands that the community wants to use: https://github.com/appsmithorg/appsmith/issues/11281#issuecomment-1249777878

Describe the improvement

Document what Redis commands we do support.

Why do you think this change is needed?

Users can clearly understand the supported features.
