feat: enable EnableRemoteLinkPicker WOPI flag for Collabora Online

Set EnableRemoteLinkPicker: true in CheckFileInfo response so
Collabora Online exposes its "Smart Picker" UI for link
insertion. Clicking it sends a UI_PickLink postMessage to the WOPI
host, which is expected to reply with Action_InsertLink carrying the
URL of the selected file. Follows the same pattern as the existing
EnableInsertRemoteImage / EnableInsertRemoteFile flags.

+Enhancement: Enable EnableRemoteLinkPicker WOPI flag for Collabora
+
+Set `EnableRemoteLinkPicker: true` in the CheckFileInfo response so that
+Collabora Online exposes the "Insert Link" UI backed by the WOPI host. When
+the user picks this option, Collabora sends a `UI_PickLink` postMessage that
+the WOPI host is expected to answer with `Action_InsertLink` carrying the URL
+of the selected file.
