Github pages website not up-to-date

[sandreae]

I noticed that the hosted docs here: https://droogmic.github.io/ are out of date wrt this repository.

Thanks for this resource, I'm starting to work through it now, if I find any required updates I'll open a PR.

I believe, this work was continued here: https://docs.rust-embedded.org/discovery/microbit/
