Ensure newline at end of `_modidx.py`

[yasirroni]

It is always nice that a file that we write is ended with an extra blank of line. I know that _modidx.py is automatically generated and we also can exclude pre-commit hook, but please consider to add a blank line in the end of _modidx.py to avoid error by end-of-file-fixer?

Below is my pre-commit regarding this.

  # nbdev clean and export
  - repo: https://github.com/fastai/nbdev
    rev: 2.2.10
    hooks:
    - id: nbdev_clean
    - id: nbdev_export

  # check yaml and end of file fixe
 - repo: https://github.com/pre-commit/pre-commit-hooks
    rev: v2.5.0
    hooks:
      - id: check-yaml
      - id: end-of-file-fixer
        exclude: LICENSE|^PACKAGENAME/_modidx.py

Good idea!

While you are at it, consider also apply it on sidebar.yml

What do you think about the sidebar.yml? It also didn't has the extra end of file line

Done!
