What this PR does / why we need it:
#4645 recently introduced the visualisation of default values for template variables.

This PR slightly improves this by ensuring that for well know variables:

  • if the template defines defaults, those are considered
  • if variables are provided with env vars, those are considered
  • if a default value is provided (no matter if in the template or by other means), the variable is listed a optional; otherwise the variable is listed as required.
