Add support for Redis 6.2

[rhymes]

Redis 6.2 has officially been released, its release notes contain quite a few new commands, improvements and some changes in behavior.

I'm new to this library but I'm willing to help. I'd imagine the first step is to add Redis 6.2 to the GitHub test actions and have the existing tests pass before starting to tackle new things.

I opened a "general" issue, but I guess this should be then split into separate issues/PRs for new commands and features.

This for example is list of new commands:

Here is a comprehensive list of changes in this release compared to 6.0.9,
each one includes the PR number that added it, so you can get more details

The list of new features:

New features:

  Has flags to enable full O(N) validation (disabled by default).
* ACL patterns for Pub/Sub channels (#7993)
* Support ACL for Sentinel mode (#7888)
* Support getting configuration from both stdin and file at the same time (#7893)
  Lets you avoid storing secrets on the disk.

There's much more, detailed in the long release notes.

I'll begin by sending a PR to add 6.2 to the test matrix

@rhymes You can check off XAUTOCLAIM #1018 .

So are we waiting until all of these have been implemented before releasing a new version of the gem? Does the gem version follow the Redis version it supports?

@alexmreis checked! For the rest, I am not sure :) I'm not a maintainer, I just opened this issue ticket to keep track of all the new changes

So are we waiting until all of these have been implemented before releasing a new version of the gem?

No. Releases happens when there's enough features to justify it, or when there's an important bugfix.

Other Redis 6.2 commands will be supported when someone submit a PR for them, or if I somehow I get time to do it myself.

Does the gem version follow the Redis version it supports?

Nope.
