Add additional link to the DMP full text

[mariapraetzellis]

We have received feedback that the link to view the full text of a publicly available plan is not noticeable enough.

Need to determine where on the page we could add a link. Two ideas:

1. Modify the "Citation" section to "Citation and Narrative" and include the link to the full text here (when available)
2. Include it in Project Details and title the field "DMP Narrative"
