Current Behavior

In utils init.py

def import_redis():
    _check_library("redis")
    _check_library("redis_om")

The library name is wrong for redis_om, instead it should be redis-om.
Refer: https://github.com/redis/redis-om-python

Which creates error when running gptcache dependent libraries:
2023-09-20T05:39:32.596024342Z stderr F gptcache.utils.error.PipInstallError: Ran into error installing redis_om.

Expected Behavior

Should install redis-om package

Steps To Reproduce

Just install and run the latest code.

Environment

No response

Anything else?

If its okay, i made a quick PR.
