qmllint: Unexpected type for property "columnWidthProvider" expected function got function

      With current qqtdeclarative dev I got new warning that "function not function" for columnProvider.

      For code from here: https://doc.qt.io/qt-6/qml-qtquick-tableview.html#row-heights-and-column-widths 

      import QtQuick

TableView {
    id: tableView

    property var columnWidths: [100, 50, 80, 150]
    columnWidthProvider: function (column) { return columnWidths[column] }

    Timer {
        running: true
        interval: 2000
        onTriggered: {
            tableView.columnWidths[2] = 150
            tableView.forceLayout();
        }
    }
}

      qmllint reports:

      Warning: Test.qml:7:26: Unexpected type for property "columnWidthProvider" expected function got function
    columnWidthProvider: function (column) { return columnWidths[column] }
                         ^^^^^^^^^

    QmlLintQuickPlugin: Warn about unexpected property binding types
    
    Sometimes we use var or Item property types when we actually expect
    some very specific types. We warn about these at runtime, let's also
    warn in the linter.
    
    Task-number: QTBUG-102859

      buggy warning disappears.
