This reverts commit 6c9b23ed, reversing
changes made to 085abd5f.

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.

note: there aren't any existing tests on what happens when the query input changes in the QuickPick
