      Description of problem:

      setting key beging "a" for platform.gcp.userLabels got error message which doesn't explain what's wrong exactly

      Version-Release number of selected component (if applicable):

      4.14.0-0.nightly-2023-10-15-164249

      How reproducible:

      Always

      Steps to Reproduce:

      1. "create install-config"
      2. edit the install-config.yaml to insert userLabels settings (see [1])
      3. "create cluster" 

      Actual results:

      Error message shows up telling the label key "a" is invalid.

      Expected results:

      There should be no error, according to the statement "A label key can have a maximum of 63 characters and cannot be empty. Label must begin with a lowercase letter, and must contain only lowercase letters, numeric characters, and the following special characters `_-`".
