Update EIP-721: Spell collectible consistently

[christopheradams]

Change the spelling of "collectable" to "collectible", to match the spelling in the rest of this and all other EIPs.

This is consistent with definitions that differentiate between items to be collected (like "collectable payments") and items of value worth collecting (like "collectible cards"). The latter is the intended meaning of NFTs.

Thank you for sharing. The meaning and intent of the EIP is clear, but the language use appears to be incorrect, I appreciate you bringing this up.

Perhaps the Google Ngram database can be helpful in studying how English is used. And that source supports the correct spelling as collectible cards.

I won't block this, but I am not convinced enough to approve it

Thank you. As a pure play, I'm addressing some of the linter errors here: #7550

If I can merge that and a couple others the hopefully your PR can be merged more smoothly.

I'm honored.
