In elastic#57701 we changed mappings merging so that duplicate fields specified in mappings caused an exception during validation. This change makes the same exception thrown when metadata fields are duplicated. This will allow us to be strict currently with plans to make the merging more fine-grained in a later release.

In #57701 we changed mappings merging so that duplicate fields specified in mappings caused an
exception during validation. This change makes the same exception thrown when metadata fields are
duplicated. This will allow us to be strict currently with plans to make the merging more
fine-grained in a later release.
The tests are marked as
@AwaitsFixas we intend to change the behavior soon to be finer-grained, and they will be beneficial once we do have the fine-grained merging.
