Discontinue support for CommonJS `require()`

[catplvsplus]

In the future major update, support for CommonJS will be dropped and all the packages will be using ES Modules. This means that using require() to import packages will no longer work and will only work for import().

Reasons

• Discord.js breaks types when importing from cjs and mjs
• ESM features cannot be utilized because of the support for CJS
• CJS is old and not the standard for importing packages

Visualization

- const { RecipleClient } = require('@reciple/core');
+ import { RecipleClient } from '@reciple/core';
