WP/CapitalPDangit: add tests using typed class constants

This commit adds a few tests using type class constants to the `WordPress.WP.CapitalPDangit` tests. This is just to ensure that the part of the sniff code that checks for `T_CONST` tokens to ignore constant declarations using the `const` keyword works correctly with typed class constants added in PHP 8.3.

The sniff was already handling typed class constants correctly, and no change to the sniff code is needed.
