Commit Message

core: Clarify missing content-type on HTTP error responses (#12720)

## Summary

In this case, grpc-java preserves the HTTP status-based context, but may
later append `invalid content-type: null`.

That seems misleading when the response is missing `content-type`,
because the header appears to be absent rather than invalid, and the
`null` value exposes a Java implementation detail.

This PR keeps the existing HTTP-to-gRPC status mapping unchanged and
only adjusts the diagnostic for the missing `content-type` case.

 ## Changes
 
- keep the existing HTTP-to-gRPC status mapping unchanged
- keep the existing behavior for invalid non-null content-types
unchanged
- replace `invalid content-type: null` with `missing content-type in
response headers`

Ref #12418
