refactor(discord-utilities): switch to jdecked twemoji fork

[SerenModz21]

Discord has switched to using Justine De Caires' (jdecked) Twemoji fork. Justine is an ex-Twitter employee who off the top of my head, used to work on Twemoji but got laid off during the layoffs after Elon bought Twitter/X. Therefore, switching Sapphire's regex to using said fork would be better suited.

Benefits of this change:

• Adds support for Twemoji v15
• Uses the same version as Discord
• More updated than the original Twitter repo

Sources:

• https://x.com/DiscordPreviews/status/1640809457423732763 Discord Previews mentioned the switch back on the 28th of March 2023.
• https://github.com/discord/twemoji Discord's Twemoji repo is a fork of Justine's fork.

Thank you for your review Vlad! The script was the first thing that I changed and ran it afterwards to update the actual code, since it gets overridden anyway.
