Fix input root url compare by normalizing

[MQ37]

When checking if the current url is the input root there may be issue with the trailing / if there is redirect. So instead of adding description and detail to top heading it is added as another link in the Index section.

Output for https://kopecky.io:

# kopecky.io

## Index

- [kopecky.io](https://kopecky.io/)
- [kopecky.io](https://kopecky.io/blog)
- [kopecky.io](https://kopecky.io/about)

Output for https://kopecky.io/:

# kopecky.io

## Index

- [kopecky.io](https://kopecky.io/blog)
- [kopecky.io](https://kopecky.io/about)

Fixed by normalizing the urls before comparing them by removing the trailing /.
