/**
 * Securely retrieves a key from Redis if it exists.
 *
 * This function first checks if the key exists in Redis.
 * If the key exists, it retrieves the value associated with the key.
 * If the key does not exist, it returns a Redis error indicating that the key does not exist.
 *
 * # Arguments
 * * `conn` - A mutable reference to the Redis connection.
 * * `key` - The key to retrieve from Redis.
 *
 * # Returns
 * * `Ok(String)` - The value associated with the key if it exists.
 * * `Err(redis::RedisError)` - An error if the key does not exist or if there is an issue with the Redis connection.
