versioning strategy

[davidecarpini]

it would be nice to have a versioning strategy

something like a backend v1: https://vechain.github.io/app-hub/index.json v2: https://vechain.github.io/app-hub/v2/index.json

we create tags for every version and we create a github action that creates a build on every tab

and then we store the current version on the package-json
