Added default appearance definitions in examples/forms.rs to match expected behaviour.

Added default appearance definitions in examples/forms to match expected behaviour, as without them, text to be displayed disappears after input until the document is saved and reloaded.

I could detect no difference in Acrobat and Preview. Could you explain in more detail what this is supposed to fix or share a screencast?

I'm not that familiar with PDF forms. The example was contributed by @tingerrr. Maybe he knows more?

[tingerrr]

I'm not sure, I don't remember that being a problem for input fields in the viewers I tried, but it has been a while, so this could have changed.

Ah, before this patch both evince (gnome) and okular (KDE) haven't properly displayed the content in the form fields, this patch fixes it. Though, this seems to only fix it for the text field at the top for me, the rest is still hardly visible (in Okular this is fixed by clicking "show forms", in evince they're just invisible).

@obreidenich Any thoughts on this?

Sorry for the long absence.

Yes, this only fixes the appearance stream on Okular and, frankly, whatever PDF reader i was using on Android at the time.

I just assumed this was a forgotten line/feature when diving into krilla/forms.
