Bump version v3.9.0

This PR implements a new lua function and packet used for sends dialogs
to the client.

## Example:


https://github.com/user-attachments/assets/97bb5813-ea12-4b1d-a049-2f7ebf6b6da3

Example serverside code:
```lua
--MP.ConfirmationDialog(player_id: number, title: string, body: string, buttons: object, interaction_id: string, warning: boolean = false, reportToServer: boolean = true, reportToExtensions: boolean = true)

function onChatMessage(player_id, player_name, message)
    MP.ConfirmationDialog(player_id, "Warning", "Watch your tone buddy!!", 
        {
            {
                label = "OK",
                key = "dialogOK",
                isCancel = true
            }
        }, "interactionID", true)
end

MP.RegisterEvent("onChatMessage", "onChatMessage")


function dialogOK(player_id, interaction_id)
    MP.SendChatMessage(-1, MP.GetPlayerName(player_id) .. " clicked OK")
end

MP.RegisterEvent("dialogOK", "dialogOK")
```

### Details:
Each dialog can have multiple buttons, each button having it's own
callback event (`key`).
Each dialog can also have one button with `isCancel` being true,
settings this property to true causes the button's event to be called
when the users pressed `esc` to exit out of the dialog. If a dialog is
created without any button being the cancel button then the user will
only be able to exit the dialog by restarting the session or pressing
one of the buttons.

`interaction_id` will be sent as the event data with a button press
event, to track from which dialog the button press came. As when
multiple dialogs are opened they will stack and it will become difficult
to track what button on which dialog was pressed without having multiple
event handlers.


Waiting on https://github.com/BeamMP/BeamMP/pull/715 to be merged.

(on Linux), you could build with  `make BeamMP-Server`, `make -j BeamMP-Server` or `cmake --build . --parallel --target BeamMP-Server` . Or, on Windows, (in Visual Studio), you would just press some big green "run" or "debug" button.
 10. When making changes, refer to [this section on how to commit properly](#how-to-commit). Not following those guidelines will result in your changes being rejected, so please take a look.
 11. Make sure to add Unit-tests with `doctest` if you build new stuff. You can find examples all over the latest version of the codebase (search for `TEST_CASE`).
