Remove `@types/twemoji`

[Chitoku]

The type definitions bundled in twemoji have the following problems, hence the need for @types/twemoji:

• They lack the test() method
  • It has already been fixed on master but no release has been created since v14.0.2.
• They only support default exports
  • In order to default import twemoji, #4236 has to be resolved as well.
