Optional Php and DocTypes in Type classes

[TiiFuchs]

In the following example the PHP type is ?PhotoSize, but in the PhpDoc it only says PhotoSize.

https://github.com/telepath-php/telepath/blob/6fd31204b0969ab86e1b0a8fa4c9b1b4470ef0cb/src/Telegram/StickerSet.php#L41-L58

I think the ?PhotoSize comes from the Laravel Pint reformatting after generation, because it recognizes the = null and adjusts the type accordingly.

But it would be nice to be consistent with both.

Probably both can be achieved by checking if the type is optional in Type::buildPhpType and Type::buildDocType. (Needs to be passed in \App\Telegram\Types\Field)
