So obviously we should convert the cases to boolean/integer. However worth noting all J3 sites won't be converted - so we'll be handling both cases for at least the forseeable future (there probably are ways to try and force the conversion by running a save through the global config controller - but don't see any reason to force it - at least for now)

But Joomla 4 clean install and Joomla 4 saving configuration should pick a side and stick to it, there is no reason one should use a bool and one should use an int... regardless if the code reading those later on can use either.

PR [4] filter to bool the cache_platformprefix and debug_lang_const on save #34148
