`Microsoft.Extensions.Caching.StackExchangeRedis` not working with IPv6 because using an old version of `StackExchange.Redis`

See original GitHub issue

Is there an existing issue for this?

Describe the bug

When using Microsoft.Extensions.Caching.StackExchangeRedis on a single-stack IPv6 cluster, we are unable to communicate with a redis database:

Can't access cart storage. StackExchange.Redis.RedisConnectionException: It was not possible to connect to the redis server(s). UnableToConnect on redis-cart:6379/Interactive, Initializing/NotStarted, last: NONE, origin: BeginConnectAsync, outstanding: 0, last-read: 0s ago, last-write: 0s ago, keep-alive: 60s, state: Connecting, mgr: 10 of 10 available, last-heartbeat: never, global: 252s ago, v: 2.2.4.27433
   at StackExchange.Redis.ConnectionMultiplexer.ConnectImplAsync(ConfigurationOptions, TextWriter ) in /_/src/StackExchange.Redis/ConnectionMultiplexer.cs:line 879
   at Microsoft.Extensions.Caching.StackExchangeRedis.RedisCache.ConnectAsync(CancellationToken )
   at Microsoft.Extensions.Caching.StackExchangeRedis.RedisCache.GetAndRefreshAsync(String, Boolean, CancellationToken )
   at Microsoft.Extensions.Caching.StackExchangeRedis.RedisCache.GetAsync(String, CancellationToken )
   at cartservice.cartstore.RedisCartStore.GetCartAsync(String) in /app/cartstore/RedisCartStore.cs:line 104

It turns out (like described here) that Microsoft.Extensions.Caching.StackExchangeRedis is using a very old version of StackExchange.Redis: 2.2.4 - defined here. But in 2.6.62 this issue was fixed in StackExchange.Redis. Is there any plan to upgrade that old 2.2.4 to a most recent version in Microsoft.Extensions.Caching.StackExchangeRedis?

Expected Behavior

Microsoft.Extensions.Caching.StackExchangeRedis should work on IPv6 stack.

Steps To Reproduce

You need to have a single-stack IPv6 cluster.
