bug: GestureDetector throwing an `Event` for on_secondary_tap, not `TapEvent[GestureDetector]`

Describe the bug

When I was writing the logic to handle the events thrown by GestureDetector, I found that when I performed a right-click operation, GestureDetector did not generate a TapEvent as described in the documentation, but a regular Event object, which caused my attempts to get the cursor coordinates to fail.

Code sample

Code

import flet as ft


def trigger_open_menu(
    event: ft.TapEvent[ft.GestureDetector] | ft.LongPressStartEvent[ft.GestureDetector],
):
    print(event)


async def main(page: ft.Page):
    # on web, disable default browser context menu
    if page.web:
        await page.browser_context_menu.disable()

    gd = ft.GestureDetector(
        on_long_press_start=trigger_open_menu,
        on_secondary_tap=trigger_open_menu,
        content=ft.ListTile(title=ft.Text("Test"), subtitle=ft.Text("Testing")),
    )
    page.add(gd)


if __name__ == "__main__":
    ft.run(main)

To reproduce

1. Run the repro code
2. Long press the ListTile
3. Right-click the ListTile
4. See the console output

Expected behavior

When I right-click, the console should output TapEvent(...).
