Can't charge crossbow with air

Before NBT became a component, a crossbow could be charged with air and fired blank shots. Also, it was previously decided not to fix this. (MC-260882)

However, now that it is a component, the crossbow can only be charged with items that exist as items, and cannot fire blank shots.

For example, the following command will fail to run:

/give @p crossbow[charged_projectiles=[{id:"air",count:1}]] 1
