Add check on CI to compare more files

[fcollonval]

Fixes #120

This approach uses the suggestion of applying the upgrade script

[fcollonval]

Should we copy the following files in the upgrade script:

      - name: Check config files
        if: steps.filter.outputs.extension == 'true'
        run: |
          diff basics/hello-world/tsconfig.json ${EXAMPLE_FOLDER}/tsconfig.json
          diff basics/hello-world/.eslintignore ${EXAMPLE_FOLDER}/.eslintignore
          diff basics/hello-world/.eslintrc.js ${EXAMPLE_FOLDER}/.eslintrc.js
          diff basics/hello-world/.gitignore ${EXAMPLE_FOLDER}/.gitignore

so that this check can be removed?

This is ready for review

Should we copy the following files in the upgrade script:

Would that affect how the upgrade is script is run locally? For example would we need to set the EXAMPLE_FOLDER variable?

Maybe it's fine to keep them separate for now.

Closing as the structure evolved quite a lot
