Remove baseUrl that didn't work
From what I've understood, there isn't a way for us to use the baseUrl for
absolute imports without also using a bundler. The baseUrl works for the
tsconfig, but not for the generated JS.
Since this setting was anyways not working, remove it. Tested by doing `yarn
dev`, `yarn build` and also doing a quick perusal in VSCode to see that it is
not reporting any errors.
