[cloud] Fix logical flaw in route53_health_check, use string ports everywhere (#25706)

* Fix logical flaw (update when diff), use string ports everywhere

* Change port comparison to integer vs. string

The comparison works either way as long as it's consistent. Boto docs
state that it takes in an integer, but if given a string apparently
keeps it as such. This change just ensures that when we compare, we
specifically deal with integers.
