- configure `@eslint-react/eslint-plugin` in eslint config
- modernize `lint` command in `package.json`
- disable or fix various reported lint issues
- fix `div` being nested in `p` for settings
- replace deprecated `event.keyCode` with `event.key`
- update isEscKeyPress method and unit tests which used deprecated `event.keyCode`
- allow `eslint` v8 as peer dependency for `@eslint-react/eslint-plugin`
