Should Microsoft.Extensions.Http.Polly be deprecated in favour of Microsoft.Extensions.Http.Resilience?

### Is there an existing issue for this?

### Is your feature request related to a problem? Please describe the problem.

`Microsoft.Extensions.Http.Polly` references `Polly.Extensions.Http`, the latter of which is marked as deprecated and tells you to use `Microsoft.Extensions.Http.Resilience`, so should `Microsoft.Extensions.Http.Polly` continue to exist in a non-deprecated form? If so, when should one use `Microsoft.Extensions.Http.Polly` over `Microsoft.Extensions.Http.Resilience`?

It is also quite confusing for `Microsoft.Extensions.Http.Polly` to exist as a v8 package when it doesn't actually reference v8 of Polly.
