In Spring Boot 3.x with Jackson 2, a null (or missing) value for
a primitive would be mapped to the primitive's default value. In
Jackson 3, the default behavior is to fail instead. This causes a
failure when trying to deserialize Podman's
`docker context ls response` as it is not in the expected format
and has no entry for `current` that's mapped to a boolean.
This commit disables FAIL_ON_NULL_FOR_PRIMITIVES to restore the
behavior that we had with Jackson 2 in Spring Boot 3.x.
