Forms blocked due to use of deprecated "is_html5_enabled"

[Vinobe93]

In the class "GF_Zero_Spam" in method "add_key_value" the function RGFormsModel::is_html5_enabled() is used.
Gforms throws an warning on this that the function is deprecated with no fallback.

I'm refering to this line:

If I change the function call to an hardcoded "true" (which is also the fallback for the deprecated function in gravityforms) the form is displayed again as it should.

Expected result: Not showing a php warning and showing the form

Edit: the issue only shows when define( 'WP_DEBUG_DISPLAY', true ); is set obviously, which is the case on our development environment. But it is a deprecated function nonetheless and should be removed.
