Change link classes on edit_record markup
Problem/Motivation
The link for adding a contribution or loging in to add one is using a `primary-button` class. However, bluecheese has adopted BEM class names, so the formula to get a primary button is to use `button button--primary` classes.
Steps to reproduce
Spin up the drupalorg D10 site locally and visit one of the contribution record test nodes.
Scroll down to the "Attribute your contribution" detail and open it up. Observe that the button is styled like a standard link. Observe that it has the `primary-button` class.
Proposed resolution
Add the classes.
Remaining tasks
User interface changes
API changes
Data model changes
