'Add Bookmark' Button on a Resource (from SRP) UI

[katerina-kossler]

Acceptance: Button with Add Bookmark button on each expanded result on a search results page (SRP).

Design notes: figma

Notes:

• two states before and after bookmarking: Add Bookmark and Bookmark Added
• might want to wait for Modal and API so we can hook up functionality.

Open Questions:

• figma suggests no bookmark removal from this view; @richardxia is following up with Research/Design teams to see if we want to support that
