chore: switch to NPM dependency for digiid-ts and update docs

- Update package.json to use the 'latest' version of 'digiid-ts' from NPM instead of the local file path.
- Run 'npm install' to fetch the package from the registry.
- Correct the 'dev:backend' and 'dev' scripts in package.json to fix the build process after the dependency update.
- Update the repository clone URL in README.md to the correct address.
