GetConfigurationErrors for workflows

[bjarnef]

Describe your idea

Field types, e.g. reCAPTCHA (or any other lookup of external data) often requires keys configured and therefore the GetConfigurationErrors() method is useful as the field type is registered, but disabled on environments, where keys are not configured.

Example from reCATPCHA:

public override IEnumerable<string> GetConfigurationErrors()
{
    if (string.IsNullOrWhiteSpace(_config.SiteKey) || string.IsNullOrWhiteSpace(_config.PrivateKey))
    {
        yield return "reCAPTCHA v3 requires SiteKey and PrivateKey to be configured.";
    }
}

However it doesn't seem a similar feature is available for workflows.

E.g. it would be useful in workflows for Mailchimp, Campaign Monitor, MailerLite or the following example in Brevo, where it currently doesn't register workflow if API key is not configured.

This feature will be coming to Forms 17.5 and 18.1 to match with how FieldTypes report configuration errors

The change has now landed in the final 17.5.0/18.1.0 release
