Render ReCaptcha Error message as Html.Raw() rather than as-is

There is a nice field to add an "Error Message" when configuring the ReCaptcha question:

It would be great if this could be rendered out such that any included HTML tags were parsed, rather than encoded. This would allow some simple formatting and clickable links, if desired.

Note - there are potential security issues with rendering using Html.Raw, but we could instead look at making this available as a rich text field, like we are introducing in #873.

That would solve it for my use-case!
