feat: change Header value input and Field Injection value input to text areas

[jarekdanielak]

Proposed Changes

As a user I want to be able to conveniently put multiple lines of text into Header value input and Field Injection value input.

Updated dependency to @bpmn-io/properties-panel as the new version has a fix for UX of text area. Don't want to introduce new text areas that I know would be bugged.
