Use matrix-doc emoji data for emoji verification i18n
Per the Matrix spec:
Clients SHOULD show the emoji with the descriptions from the table, or appropriate translation of those descriptions. Client authors SHOULD collaborate to create a common set of translations for all languages.
The translation set is available on the matrix-doc repo: https://github.com/matrix-org/matrix-doc/blob/main/data-definitions/
The idea would be to integrate those translations with our translations at build time so the use is seemless in the code.
Based on #893 (closed).
