Emoji: Update Twemoji to version 2.2.5 

Updates Twemoji and adds a second Emoji 4 test to include a shrugging man. Emoji 4 is being implemented gradually, while some browsers now support the female technologist, the indifferent shrugging man is breaking things with his presence.

Props peterwilsoncc, pento for code review.
Fixes #40615.
