11 - Fork & merge: Add annotations sidebar to contribution merge pane
SUMMARY
The contribution merge pane should have the annotations sidebar loaded with the annotations of the contribution document.
When the contribution merge pane is open the original annotations sidebar should not be on the right side of the scree but on the right side of the document editor.

This sidebar should be a separate instance of the current annotations sidebar for the original document.
The original sidebar and the sidebar of the contribution pane should not be able to open concurrently. On opening one instance the other should collapse.
The contribution annotations should be loaded from a different api call to the leos-annotate-module (@khandsh could you please provide the api?).
In the contribution annotations sidebar only comments and highlights should be visible (not suggestions)
On highlighting text in the view and merge contribution pane no annotation popup with actions should be present. The user must not be able to create new annotations.
All actions in the contribution annotations sidebar should be disabled/not present except the search and sort.
When annotations are present in the contribution document corresponding highlights and lines should be visible
