If multiple instances of the same  custom editor are opened for the same resource, the edit stack should be shared between them. This matches how we work with text files

For #85160

Summary:
Address issue #73904 by adding an optional `sortByLabel` to the QuickPick class which determines whether the picker re-sorts the result list when the user types in the input field.

If true, the picker applies a sort to order results by the index of the first appearance of the input in the label.

For backwards compatibility, this field is true by default.
