Misc changes (#17)

* changes after running npx update-browserslist-db@latest

* management: remove files not related to this repo

* fix: changes after running npm audit fix

* fix: npm run docs:build

It was appearing the following error everywhere on logs:
[vuepress] No matching page found for sidebar item "/zh/developing/cache/"

This was not allowing the build to finish as expected

* docs: required node version marked in README
