refactor: rewrite to djs v14

[kyranet]

👀

Changes

• Upgraded Yarn from v3 to v4.
• Downgraded Node.js CI version from 20 to 18 (and pinned to v18 with Volta) because import loader issues in Workers with Node.js v20. See: New --import API breaks worker threads privatenumber/tsx#354
  • Because the loader in v18 can resolve .ts in Worker's constructor, and is required to be passed in the arguments (rather than done at runtime), scripts/workerTsLoader.mjs was deleted.
• Switched from jest to vitest for better test performance.
• Switched from ts-node to tsx for better support in Node.js v18 and upwards (uses esbuild under the hood as well). Removed ts-node altogether.
• Switched from CJS to ESM.
• Updated discord.js from v13 to v14.
  • Updated discord-api-types/v9 to discord-api-types/v10 to match.
• Updated @sapphire/framework from v2 to v5.
• Updated typeorm, giving them a last chance. Skyra now uses less relationships, so it should be probably fine.
• Split SkyraCommand (extends Subcommand) into SkyraCommand (extends Command) and SkyraSubcommand (extends Subcommand).
• Removed PaginatedMessageCommand, replaced with Skyra{Subc,C}ommand.PaginatedOptions to reduce code duplication.
• Removed old v7-* commands. Kept v7-artiel since it's newer and expected to be used soon.
• Removed unused DB structures (banners and client).
• Removed left-over API route from the social module (/banners).
• Removed TriviaManager tests, they're being removed soon in favour of Artiel.

Extras

• Updated s!conf's menu to listen only to reactions on the menu's message
• Updated s!dice to default parameter-less to 6
• Updated getImage to fallback to stickers when there are no attachments
• Updated channelName argument to throw a less misleading error when filter returns false
