Update Emojibase and switch to IamCal (Slack-style) shortcodes

for consistency with shortcodes commonly used by other platforms, as
was decided in https://github.com/vector-im/element-web/issues/13857.

One thing to be aware of is that the currently used version of Twemoji
does not support a few of the newer emoji present in Emojibase, so these
look a little out of place in the emoji picker. Optimally Twemoji would
be updated at the same time, though I don't know how to do that.
