Allows users to exclude DefaultMismatchedInputException

A few users have run into an issue where
they are trying to handle all Jackson exceptions
but the existence of DefaultMismatchedInputException
prevents that for MismatchedInputException
(as per JAX-RS / Jakarta REST rules).

This change allows users to do use:

quarkus.class-loading.removed-resources."io.quarkus\:quarkus-rest-jackson"=io/quarkus/resteasy/reactive/jackson/runtime/mappers/DefaultMismatchedInputException.class

in order to have Quarkus ignore the mapper.

(cherry picked from commit 7f09b8c)
