Many missing returns

Whao, there are some heavy ones... @benstallings wouldn't it make sense to also add the return types on these methods?

@anybody only if the parent classes support it. I didn't look into these specifically, but my experience has been that defining a return type in a child class's method can make it incompatible with the parent's method, so I didn't mess with that, I just addressed the phpstan warnings.

@benstallings correct - that should only be done if the parent class does it. Could you check that?

Also the MR has conflicts that need to be resolved. Guess you should have clicked "Update fork" before changing things manually :(

@anybody I resolved the merge conflict, but I do not find any parent classes of these classes that specify return types. If you know of one that is relevant to this ticket, please let me know which one you're referring to. Thanks!

Thanks @benstallings - @grevil please do a quick review and then let's merge this. Quite some wild things found ;)

That's wild... Especially, that "src/Plugin/EntityBrowser/Display/Standalone.php" is a live Entity Browser Display... I doubt that it is working at all 😅

@benstallings thanks for the fixes! 👍
