The syntax "ElementInterface | null" is only supported since PHP 8 and breaks this bundle in Pimcore 6. Changed to ?ElementInterface.

Hello,

I just intalled today again the extension and went on the problem I mentionned a few month ago  pimcore#94
I think it is better to update the install documentation with this additionnal parameter so install is fluid with no problem for people trying the extension.
(it tooks me some times to remember how to bypass this problem, so if it is directly on the install command on the documentation, no need to dig to find how to install it on Pimcore 10!)

Thanks,
Best regards
