Heyo, wow am I a huge fan of the project :) yall just shaved like 80% off our build time!

A quick heads up that this page needs a proofreading pass: HMR FAQ | https://github.com/web-infra-dev/rsbuild/blob/c1fb66b6ac0b13c33848f802d679b85125e7e585/website/docs/en/guide/faq/hmr.mdx

If you're short on editors I'm happy to give it a once over 🍻
