Description
Currently we cannot specify hint both using @Query or @Hint annotation that could be resolving the value from parameters. For example, The following should work:
@Query(
value = "{ something: ?0}",
hint = "?1"
)
@Hint
Flux<Somthing> findSomething(String something, String hint);
This is working for @Query.value, but as well for @Query.collation (see docs) and not for the hint.

Research direction
Start by tracing how repository query parameters are resolved for @Query.value and @Query.collation, then compare that path with hint handling through @Hint. Use the example in the issue as the starting case. Done means a hint value such as "?1" resolves from the method parameters and the behavior is covered by regression tests.
