fix: remove yarn.lock and restore rc files (#122)

* chore: remove yarn.lock and restore rc files

We currently use two packagers: npm and yarn. This is bad, and I thus propose to switch to npm.

Furthermore, in the vite PR we removed some .*rc files, which does not seem nessescary as far as I understand,
and it would be better to keep them.

* installed latest eslintrc

* feat: added editorconfig

* removed old files

* removed jshint

* chore: simplified .eslintrc.json
