Exclude ClassConstantTypeHint because we support older PHPs too

Need to bump the coding standard because otherwise phpcs complains that "Referenced sniff does not exist" even if excluded.

I could still add docblock types for the constants, but let's not go there and wait until only PHP 8.3+ is supported (don't hold your breath).

New spaze/coding-standard adds the rule
