fix(EWT-543): type change for description field in authorization flow actions objects

[dili91]

Description

Warning

This is a breaking change from the library perspective.

Fixes a long time oversight: the description field in form actions objects was implemented as String, but it's of type DisplayText.

Unfortunately this is a breaking change at compilation time.
