FileUploadForm support

Here's a patch for those who need a quick workaround (which ignores the config if no entity exists). As this is not a solution, i didn't create an issue fork or mr.

Thanks for calling out the issue. There’s nothing worse than turning on a module and discovering an error. If you have repro steps or details on the field types used, I’d be glad to see them. I drafted a fix but have run out of time. I do expect to have it ready Sunday.

I’ve created pull request that simplifies checking if the decorative checkbox added and where the we get the configuration. This avoids the getEntity() and should solve error.

I’ve gone thru testing on 9.5 and 10 but I’ll give it another look at the start of the week before merging.

Thanks again for raising this issue. Any feedback welcome.

Release 1.3.3 created.
I'll finish last testing once packaging is complete, which should be shortly.

Tested with Drupal 11.1.7 and it works! Thanks for the quick solution
