fix: allow fullscreen for h5p iframe

[pyphilia]

Some h5p provide fullscreen feature. Before the fix it resized once and stays like this, it's impossible to revert.

I added the allowFullscreen prop for the iframe.
It does not work perfectly, one click over three resize weirdly.

Without this change, the fullscreen does not work at all, so I guess it's okay as compromise.
I quickly tried to set height=100% on fullscreen event, but it didn't work.

I just have a question about the last video. With this change, the user can easily enter in fullscreen, but then he has to click twice to exit this mode ?

Looks good ! I had a user show me this behaviour too, nice that you were able to fix it.
