Update docs for browser usage

First off, thank you so much for creating bcrypt-ts 🙂️ I was trying to run it on the browser (using Vite as bundler) without success until I noticed there's an oversight in the docs: *If you meet any issues that a incorrect bundle is used, you can use bcrypt-ts/node and bcrypt-ts/client to force the correct bundle.* For browser usage, it's __brcrypt-ts/browser__ not __client__
