Deployments history generator (via Github workflow)

[clemlak]

Description

Add a new Github workflow that will generate the deployments history when a branch is merged on main.

Motivation

Currently the deployments history is generated manually (using make generate-history), each branch might have different deployments depending on the work in progress, resulting in git conflicts before merging on main.

Proposed Solution

• Add a new Github workflow that will generate the deployments history when a branch is merged on main
• Ideally update the current workflow copy / pasting the deployments in the documentation repo
• Make sure each branch still have a way to see the newly deployed contracts? (not generating the deployments history on each chain might be an issue in that case)
