HybridCache returning null when using Poly.Outcome return type

### Description

When encapsulating a return using Poly.Outcome from the resilience framework in hybridcache, the Result return is always null. MemoryCache returns the correct response.

### Reproduction Steps

var hybridTest = await _hybridCache.GetOrCreateAsync("hybridtest", async (entry) =>
{
return Outcome.FromResult("Test");
});
var memoryTest = await _memoryCache.GetOrCreateAsync("memorytest", async (entry) =>
{
return Outcome.FromResult("Test");
});

### Expected behavior

hybridTest.Result should read "Test"
memoryTest.Result should read "Test"

### Actual behavior

hybridTest.Result is null
memoryTest.Result is "Test"

### Regression?

_No response_

### Known Workarounds

Not necessarily a workaround, but dropping the Poly.Outcome wrapping i.e:

var hybridTest = await _hybridCache.GetOrCreateAsync("hybridtest", async (entry) =>
{
return Outcome.FromResult("Test").Result;
});

Gives hybirdTest == "Test", but you are missing the Outcome wrapping
