BREAKING Use component wrapper on attachment component

[AshGDS]

What

• Adds the component wrapper to the attachment component
• This is a breaking change, as it renames data_attributes to url_data_attributes, as those data attributes were being used on a child component - data_attributes is now for data attributes applied to the parent HTML element.
• This should only affect two templates - 1 and 2 which I verified using this search criteria.

Why

As the trello card states:

Standardising our components to use the component wrapper helper will reduce code, increase standardisation, and improve future feature implementation speed.
