Grommet components reporting

[AlfredPichard]

Purpose

This PR, not aimed to be merged, adds a new config file for react-scanner to report the grommet components in marsha frontend.
Ultimately, we would like to reduce the number of grommet components that we use in marsha. This first step gives us a state of the art of the current presence of it in our code.

Proposal

The goal is to keep track of the previous report files and use the config file regularly to visualize the progression of grommet removal.
