[docs] Add a mention in the docs for adding @types/bun to the compilerOptions.types array of the tsconfig.json

Hello! 🔥🤩👋🐰🍞

I searched in Google and in the docs, and there's no mention of adding @types/bun to the compilerOptions.types array of the tsconfig.json. I get an error if I don't add it, and also don't get types completion.

Cannot find name 'Bun'. Do you need to install type definitions for Bun? Try npm i --save-dev @types/bun and then add 'bun' to the types field in your tsconfig.

Even the bun init generated tsconfig.json doesn't have it!

This is minor but it can't be used without it
