Relax JSONResponseSerializer Sendable Requirement (#3903)

### Issue Link :link:
#3902 

### Goals :soccer:
This PR relaxes the `Sendable` requirement in the value returned from
`JSONResponseSerialization`, as it breaks downstream consumers still
using `Any`.

### Implementation Details :construction:
Reverted the type returned from `JSONResponseSerializer` from `any Any &
Sendable` to just `Any`.

### Testing Details :mag:
Tests updated.
