Removing `prettier.prettierPath` allows the config file to be found
again. But from what I can tell, this option was not deprecated. So on
review, please validate that this works on your own setup as well.
* Setup stricter linting for typescript
* make `import/no-unresolved` an error everywhere
* use prettier to format `.vscode/settings.default.json`
* address PR comments
