Emoji: Update Twemoji fallback to version 2.2.2.

This removes support for the skin tone modifier on emoji involving two or more people. This functionality is opposed by Apple and Google, so there is unlikely to be an input mechanism for such emoji, they oppose it on the grounds that they "...do not think a mechanism should be supported that only permits depiction of multi-person groups (or elements) in which each person has the same skin tone."

See their official notification for further details: http://www.unicode.org/L2/L2016/16332-remove-multi-emb.pdf

This change does not require a CDN update, as no emoji were altered or added, only removed.

See #38113.
