feat: automate security release issue creation

[marco-ippolito]

This PR automates the first step of the security release: security --start. The Next Security Release issue will not contain the list of reports but they will be stored in the new repository security-release in a json format. This way it will be much easier to automate and manipulate json rather than markdown strings. @RafaelGSS
