Write a translator for yaml -> maestro.data models

[dkurepa]

Depends on #5611

Context

As condluded in #5468 (comment), the ingestor will take in Maestro.Data models.

This means that the PR Validation pipeline will have to parse the yaml with the Yaml Models and then translate them into the Maestro.Data models before giving them to the ingestor

Goal

Write a yaml -> maestro.data models translator for all yaml models.
It should probably go to the Maestro.DataProviders project

Is this issue still relevant?
Originally the converters were inside the ingestor, but now the ingestor takes yaml models anyway

true, this isn't needed anymore
