Add versions on readme wiht action to update

[AurelienFT]

Description

I added the versions used in different networks for other people to easily have the information. To avoid technical debt and maintenance I added an Action that chekcs every hour if a network has been updated and creates a PR to update the table if needed.

This has been tested on a fork of chain-configuration repository.
