A TypeScript version would be great, it's very hard to upgrade as-is

The new JS version of this came out just when I was looking to learn to make a Discord bot. It worked great after previous false starts in other languages.

But after getting to a certain point I tried to convert it to TypeScript and found it far beyond my capabilities. Especially the `deploy-command.js`

Start with deploy-command.js and the current JavaScript version to determine how much of the bot examples needs TypeScript support. Define the conversion scope and verify that a TypeScript version can be used for the examples, especially command deployment.
