Fr correction

Rework of [previous pull request](https://github.com/alessandro1997/the-codeless-code/pull/80/) + case 35 and 36.

It's [used with *pousser*](https://fr.wiktionary.org/wiki/plus_avant), which would work instead of *développer*:

  > …et souhaitaient pousser la technologie plus avant.
