Bugfix: Content Picker, gets dynamic root value from menu context

[leekelleher]

Description

In the Content Picker, (formerly Multinode Treepicker), to set the start node of the picker (using Dynamic Root), the UMB_ENTITY_WORKSPACE_CONTEXT was used to get the unique ID of the entity. However, when using the Content Picker within a Block Grid/List, the workspace context was for the Block, not the top-most entity, e.g. a document.

Rather than attempt to query the Block's modal context (for the parent entity workspace context), I have opted to use the UmbMenuStructureWorkspaceContext.structure to get the top-most entity workspace's unique and parent unique values.

(We were already using this to get the parent unique)

Fixes umbraco/Umbraco-CMS#16632.

Types of changes

• Bug fix (non-breaking change which fixes an issue)

How to test?

• Configure a Content Picker property-editor with a "Node type" of "Content" and "Specify root node". (The exact configuration doesn't matter).
• Add to a property on an element-type, then configure a Block List property-editor to use that element-type.
• Add both the Content Picker and Block List data-types to a document-type.
• Create a new document (of that type); try opening the Content Picker modal, do you get the expected results? and no error?
