build: fix fetch assets local script (#198)

* Currently the `fetch-assets-local` script tries to copy every `.html` file to the `src/assets` folder.
  This includes multiple `README.html` files. Bash at this point complains that there are multiple files with the same name are copied to the same destination.
* Also ensures that the CWD of the fetch script is always the root of the project.
