Adds graphql search options for Ml::ModelVersion

What does this MR do and why?

Adds graphql search options for Ml::ModelVersion

Adds a new resolver that allows searching through the versions of a machine learning model, along with model changes necessary to support the searching and ordering.

How to set up and validate locally

1. In rails console enable the experiment fully

   Feature.enable(:model_registry)

2. In rails console, create a model and a few model versions

   p = Project.find_by(id: 1)
   Ml::FindOrCreateModelService.new(p, "model_1").execute
   Ml::FindOrCreateModelVersionService.new(p, { model_name: "model_1", version: "2.0.0" })
   5.times { |i| Ml::FindOrCreateModelVersionService.new(p, { model_name: "model_1", version: "1.0.#{i}" }).execute }

3. Navigate to <gdk>/-/graphql_explorer and run the following query:

{
  mlModel(id: "gid://gitlab/Ml::Model/1") {
    versions(version: "1.0", orderBy: VERSION, sort: ASC) {
      nodes {
        version
        id
      }
      pageInfo {
        hasPreviousPage
        hasNextPage
        endCursor
        startCursor
      }
    }
  }
}
