Deprecate history.md file like in main Chai repository (#36)

* Deprecate history.md file like in main Chai repository

The History.md file doesn't seem to be updated any more in this repo. I can see the Chai History.md file is deprecated in favour of GitHub history (https://github.com/chaijs/chai/blob/main/History.md), so it seems sensible to deprecated this one the same way.

* Apply Deno formatting
