Update Redis adapter and storage to v1.2.0

This commit updates the Redis adapter and storage to version 1.2.0, changing the module name from "env-redis" to "env_redis". It also adds error logging for Redis load operations in the storage package. The README.md file has been updated with a new example configuration for using the updated module name in the storage block.
