Description

• Adds support for EnyimMemcachedCore versions 2.X and 3.X with nearly all methods except MultiGet methods, sync and async.
• Adds ContainerIntegration tests: (I expect these will change when net9.0 releases)
  • net8.0 with EnyimMemcachedCore v2.1.9
  • net6.0 with EnyimMemcachedCore v3.2.2
