Redis 7.2 test failures

[voxik]

A while ago, Redis 7.2 RC landed in Fedora and since that we observe several test suite issues. Trying to enable Redis 7.2 upstream (my test PR), I have hit the same failures:

  1) Failure:
TestScanning#test_sscan_with_encoding [/home/runner/work/redis-rb/redis-rb/test/redis/scanning_test.rb:142]:
--- expected
+++ actual
@@ -1,3 +1 @@
-# encoding: US-ASCII
-#    valid: true
-"hashtable"
+"listpack"

  2) Failure:
TestRemoteServerControlCommands#test_object [/home/runner/work/redis-rb/redis-rb/test/redis/remote_server_control_commands_test.rb:78]:
Wrong encoding for list

Not sure what causes them.

The reason is that set support listpack encoding since Redis 7.2.
