js-port: also skip ToastBarTopPositionScreenshotTest under chartDocumentStaleness

CI run on 23ad45d made it through 72 of 73 tests, then hung at
ToastBarTopPositionScreenshotTest. The diag log shows the same
canvas-accumulation symptom the chart tests hit:

    PARPAR:DIAG:FALLBACK:cn1ssEmitCurrentFormScreenshotDom:noCanvas=1
    PARPAR:DIAG:SCREENSHOT_START:settleReason=screenshot:ToastBarTopPosition

By the time ToastBar runs (index 72, the LAST test in the suite),
the page has accumulated ~420 hostRef-tracked canvases and the
screenshot pipeline's canvas selection emits noCanvas=1 -- same
root cause as ChartDoughnutScreenshotTest and friends. Park it
under the same chartDocumentStaleness reason. With this skip the
suite should finish cleanly: 67 tests run normally, 6 chart tails
plus ToastBar force-finalise.

Tests we expect to run now (all previously force-finalised under
the obsolete ``jsChunkDrop`` reason):
  - KotlinUiTest
  - MainScreenScreenshotTest
  - SheetScreenshotTest, SheetSlideUpAnimationScreenshotTest
  - ImageViewerNavigationScreenshotTest
  - TabsScreenshotTest, TextAreaAlignmentScreenshotTest
  - ValidatorLightweightPickerScreenshotTest,
    LightweightPickerButtonsScreenshotTest
  - All 26 tests.graphics.* cells
  - ChartLineScreenshotTest, ChartCubicLineScreenshotTest,
    ChartBarScreenshotTest, ChartStackedBarScreenshotTest,
    ChartRangeBarScreenshotTest, ChartScatterScreenshotTest,
    ChartBubbleScreenshotTest, ChartPieScreenshotTest
