Bump redis from 4.2.1 to 4.8.0

[dependabot]

Bumps redis from 4.2.1 to 4.8.0.

Changelog

Sourced from redis's changelog.

4.8.0

• Introduce sadd? and srem? as boolean returning versions of sadd and srem.
• Deprecate sadd and srem returning a boolean when called with a single argument. To enable the redis 5.0 behavior you can set Redis.sadd_returns_boolean = true.
• Deprecate passing timeout as a positional argument in blocking commands (brpop, blop, etc).

4.7.1

• Gracefully handle OpenSSL 3.0 EOF Errors (OpenSSL::SSL::SSLError: SSL_read: unexpected eof while reading). See #1106 This happens frequently on heroku-22.

4.7.0

• Support single endpoint architecture with SSL/TLS in cluster mode. See #1086.
• zrem and zadd act as noop when provided an empty list of keys. See #1097.
• Support IPv6 URLs.
• Add Redis#with for better compatibility with connection_pool usage.
• Fix the block form of multi called inside pipelined. Previously the MUTLI/EXEC wouldn't be sent. See #1073.

4.6.0

• Deprecate Redis.current.

• Deprecate calling commands on Redis inside Redis#pipelined. See #1059.

  redis.pipelined do
    redis.get("key")
  end

  should be replaced by:

  redis.pipelined do |pipeline|
    pipeline.get("key")
  end

• Deprecate calling commands on Redis inside Redis#multi. See #1059.

  redis.multi do
    redis.get("key")
  end

  should be replaced by:

  redis.multi do |transaction|
    transaction.get("key")
  end
