Removes the delete icon from attachments in the attribute help texts
dialog. This works around an issue where the attachments delete
confirmation dialog (ng implementation) opens behind the attribute help
texts dialog (Primerized implementation).
Creates the following Primerized components:
* `AttributeHelpTextComponent` to render an icon that will invoke the
attribute help text dialog on click.
* `AttributeLabelComponent` to render an attribute label and help text
icon together with the correct spacing.
* `AttributeHelpTexts::ShowDialogComponent` to render the attribute help
text dialog itself.
Also creates accompanying Controller actions, routes and specs.
* Use common helper for nested breadcrumb element
* Update app/components/attribute_help_texts/index_page_header_component.rb
