Names of file inputs with raw arguments are not properly sanitized by the compiler

[Ark-kun]

When passing output references to inputs consumed as files, everything works fine.
When passing constant strings to inputs consumed as files, the artifact names are not sanitized leading to invalid workflows.

templates:
    - inputs:
      parameters:
      - {name: model_dir_uri}
      artifacts:
      - raw: {data: ''}
        path: /tmp/inputs/Default_data/data
        name: Default data

invalid spec: templates.continuous-training-pipeline.tasks.download-from-gcs templates.download-from-gcs.inputs.artifacts[0].name: 'Default data' is invalid: Parameter/Artifact name must consist of alpha-numeric characters, '_' or '-' e.g. my_param_1, MY-PARAM-1
