Is your feature request related to a problem? Please describe

The "Go to text" link in the rendered reference card points to the target note only, not to the specific heading or a reference block which is referenced.

From https://wiki.dendron.so/notes/401c5889-20ae-4b3a-8468-269def4b4865.html.

"Go to text" points to https://wiki.dendron.so/notes/eea2b078-1acc-4071-a14e-18299fc28f47.html, but the reference card itself takes content from this heading https://wiki.dendron.so/notes/eea2b078-1acc-4071-a14e-18299fc28f47.html#initialize-workspace.

Describe the solution you'd like

• add a link to the reference target note only to the "From X" line:
  
• change the "Go to text" link to point to the exact reference target:
