Pipeline versions cannot be run on VAI

[jmendesky]

Describe the bug
Pipeline versions are persisted onto VAI runs as a label. Because VAI labels only support lowercase letters, numbers, dashes and underscores some valid pipeline versions result in VAI refusing the creation of the job.

To Reproduce
Create a Pipeline with a version containing dots, for example

apiVersion: pipelines.kubeflow.org/v1alpha5
kind: Pipeline
metadata:
  annotations:
    pipelines.kubeflow.org/provider: vai
  name: kfp-operator-quickstart
spec:
  image: ghcr.io/kfp-operator/kfp-operator-quickstart:0.4.0
  tfxComponents: pipeline.create_components
