Custom action title in flow should be the title not the Kind

[cxbuilders]

Bug is debatable, but the title in the Custom Action component in the flow should be the Title in the CA schema and not the Kind property of the CA Dialog class / file name of the schema. This would make it consistent with other components.

Thank you for the suggestion @cxbuilders, we will prioritize this in our next release.
