Update MongoDB to 2.28

[eerhardt]

Description

There was a breaking change between 2.27 and 2.28 - MongoDB.Driver added an assembly strong name.

We can now remove our NoWarn workarounds for MongoDB. Except Aspire.MongoDB.Driver still needs the NoWarn for 2 the health check and DiagnosticSource packages.

Fixes #5427
