Explicit versioning of shared libraries

[sgerogia]

Atm the shared libraries (utils, models) have implicit versioning.
If a merged change is not backwards compatible, it will cause downstream code to break immediately.

DoD

• Introduce an explicit SemVer GHA (e.g. this one) in both libraries. This will create automatic versions based on PR labels.
• It is triggered on merge
• Create the first explicit version in both libraries
• Notify other team members

• Create a base tag or release on both repos
• Decide on a release strategy

We should update versions on existing repos too as part of this issue
