docs: Return form field value from 3 options:
          1. If value key is present, render it as a Jinja2 template.
             The template has access to ``conf`` and ``creds`` dictionaries.
          2. If creds key is present, use it as a dot-delimited path
             in creds dictionary (e.g. ``account.login``).
          3. Otherwise return None
