Bug Description

We should adjust the warning message to manually check for the value if a variable or constant is being used in the 4th parameter of wp_cache_set().

Minimal Code Snippet

define( 'TEST_TIME', 5 * MINUTE_IN_SECONDS );
$time = 5 * MINUTE_IN_SECONDS;

wp_cache_set( $key, $data, '', $time );
wp_cache_set( $key, $data, '', TEST_TIME );
