Script to sync emojis files with GitLab repo

This MR adds scripts/sync_emojis.js script that copies files that are generated by gemojione ruby gem in GitLab project to the Status Page project for emojis rendering. yarn emojis currently can be run manually to sync assets.

⚠ currently there is no code in the project that consumes these assets

In scope of !62 (merged) actual rendering and consumption of these resources will be handled
