Added a hosted web version of the Rust Training content

[adarshdhital007]

I created a hosted version of this Rust training to make it easier for users to access the content without needing to clone the repository and run cargo build every time.

https://microsoft-rust-training.vercel.app/

I integrated all the existing docs from this repo into a web-based format so learners can go through the material more smoothly in the browser.

@atulkhare4096 If you think this could be useful, I’d be happy to add it to the README or adjust it based on your feedback. Thanks for the great resource!

@adarshdhital007 Can you please add it to the "Notable forks" discussion thread? It's best to avoid frequent edits of README.
