Missing `multiverseid` (+ `imageUrl`) field(s) for latest expansion

[mcottret]

Hello there !

First of all thanks for the project, I just started using it recently & it looks great !

I noticed that the multiverseid field was missing for cards of the latest expansion (currently "Ikoria: Lair of Behemoths"). Consequently, the imageUrl field is also missing.

According to the documentation, cards from this set should have this field since it exists on the Gatherer. I was wondering if this feature was still supported, or if this might be a bug.

Thanks in advance, cheers !
