Validation problem should use IProblemDetailsService in the same way as #47045

Describe the solution you'd like

I think that ValidationProblem (Microsoft.AspNetCore.Http.HttpResults) should also use the IProblemDetailsService in the same way as #47045 to be able to customize the validation problem in one place.

I just created a PR for this. I guess this will be to late for .NET 8 or can it be sneaked in for consistency reasons?

[martincostello]

At this point, I believe .NET 8 is "done" - there's no such thing as "sneaking it in" once they lock down the branches, which typically happens once they permanently branch off of main before the first release candidate.

Technically .NET 8 is still a release candidate and this is an oversight, but probably not severe enough to warrant including it in the upcoming release... But I do hope the team will consider backporting this one :)
