chore: cleanup and improve dependencies

- removed `@meetfranz/typings` because it only stubbed external type definitions
- removed `@babel/polyfill` because there are no old browsers in use with Electron
- replaced deprecated `mdi` with `@mdi/font`
- removed unused `atob`, `btoa`, `targz`, `node-fetch`, `terser-webpack-plugin`, `webpack-node-externals`
- added used, but not installed dependencies `color`, `csstype`, `debug`, `minimist`, `jss`
- upgraded `@types/node` to match used node version
- upgraded `@types/fs-extra` to match fs-extra version
- add missing `arrow-parens` rule to `.eslintrc` rulest for .js files
