Check ResponseStatusException reason as MessageSource code for ProblemDetail

detail in ProblemDetail will be localized
Closes GH-30222

The problem is that reason may or may not be a message code, and this change suppresses the default message code determination. Is there a reason you can't use the default message code, i.e. problemDetail.org.springframework.web.ErrorResponseException, or otherwise creating a dedicated sub-class also allows you to set the message code and arguments?

I'm trying to fix the inconsistency in boot spring-projects/spring-boot#34791

[rstoyanchev]

The referenced Boot issue was closed because the issue can't be addressed on the Boot side, so I don't know what you mean. Here I'm saying that the PR in its present form can't go forward because it assumes the reason is a message code, without any option to change that assumption, also suppressing the ability to use a consistent message code as for all other exceptions.

Whatever the solution, it would need to be much more explicit about passing a message code, but again I'm wondering whether switching to the default message code would work for you.

@rstoyanchev I updated the commit that will break nothing just enhancement, please review it.

@rstoyanchev Could you take a look?

[rstoyanchev]

Apologies for the delay. Yes, if used as a fallback it should work.

I have moved the change down to ResponseStatusException from ErrorResponse since it is something specific to it and doesn't need to apply to any exception.
