There is no sSubscribe method on redisClient object when using redis sentinel with node-redis

[barisusakli]

redis@5.10.0
@socket.io/redis-adapter@8.3.0

When using createSentinel from https://github.com/redis/node-redis/blob/master/docs/sentinel.md, the returned redisClient object doesn't have a sSubsribe/send_command methods. Which causes the checks in utils.js to go into the ioredis/redis@3 branch and crash. Everything works if the redisClient is created with createClient which returns an object with sSubscribe method.

The stacktrace is below.

TypeError: redisClient.send_command is not a function
