Update ML Model Versions to use semver module

What does this MR do and why?

With Adding SemanticVersionable concern to Ml::Model... (!142228 - merged) merged, this MR updates the Ml::ModelVersion to write new records to include the semver attributes. It writes the original version column, and uses the semver setter to parse and save the semver attributes to semver_major, semver_minor, semver_patch, and semver_prerelease. Once this MR is deployed, another MR will be created to add additional DB constraints and indexes for querying on the semver attributes.

How to set up and validate locally

In a local rails console run:

1. Create a model

   model = Ml::CreateModelService.new(Project.first, 'test-model').execute

2. Create a model version

   version = Ml::ModelVersion.create(model: model, project: model.project, version: '1.2.3')

3. Ensure the semver attributes (major, minor, patch) are set on the model version record
