Update redis requirement from ~> 4.2 to >= 4.2, < 6.0

[dependabot]

Updates the requirements on redis to permit the latest version.

Changelog

Sourced from redis's changelog.

5.0.6

• Wait for an extra config.read_timeout in blocking commands rather than an arbitrary 100ms. See #1175.
• Treat ReadOnlyError as ConnectionError. See #1168.

5.0.5

• Fix automatic disconnection when the process was forked. See #1157.

5.0.4

• Cast ttl argument to integer in expire, setex and a few others.

5.0.3

• Add OutOfMemoryError as a subclass of CommandError

5.0.2

• Fix Redis#close to properly reset the fork protection check.

5.0.1

• Added a fake Redis::Connections.drivers method to be compatible with older sidekiq versions.

5.0.0

• Eagerly and strictly cast Integer and Float parameters.
• Allow to call subscribe, unsubscribe, psubscribe and punsubscribe from a subscribed client. See #1131.
• Use MD5 for hashing server nodes in Redis::Distributed. This should improve keys distribution among servers. See #1089.
• Changed sadd and srem to now always return an Integer.
• Added sadd? and srem? which always return a Boolean.
• Added support for IDLE paramter in xpending.
• Cluster support has been moved to a redis-clustering companion gem.
• select no longer record the current database. If the client has to reconnect after select was used, it will reconnect to the original database.
• Better support Float timeout in blocking commands. See #977.
• Redis.new will now raise an error if provided unknown options.
• Removed positional timeout in blocking commands (BLPOP, etc). Timeout now must be passed as an option: r.blpop("key", timeout: 2.5)
• Removed logger option.
• Removed reconnect_delay_max and reconnect_delay, you can pass precise sleep durations to reconnect_attempts instead.
• Require Ruby 2.5+.
• Removed the deprecated queue and commit methods. Use pipelined instead.
• Removed the deprecated Redis::Future#==.
• Removed the deprecated pipelined and multi signature. Commands now MUST be called on the block argument, not the original redis instance.
• Removed Redis.current. You shouldn't assume there is a single global Redis connection, use a connection pool instead, and libaries using Redis should accept a Redis instance (or connection pool) as a config. E.g. MyLibrary.redis = Redis.new(...).
• Removed the synchrony driver.
• Removed Redis.exists_returns_integer, it's now always enabled.

4.8.0
