fix: Change the behavior of notify parameter in context to default to null by default

[TheoD02]

Description

The changes allow the notify property in the context to be set to null and this is the new default value.

Previously, the notify property could only be set to true or false. Now, it can be set to null, true, or false.

Here's what each value means:

• false: Notifications are disabled globally.
• null: Notifications are disabled for internal Castor run, with calls, but notify() calls triggered by the user will still show notifications.
• true: All notifications will be shown.

This change provides more flexibility for controlling when notifications are shown.

Changes

#[AsTask(description: 'Sends a notification')]
function send_notify(): void
{
    // The two tasks below will don't send a notification
    with(
        callback: function () {
            run(['sleep', '0.1']); // Will not send a notification
            notify('Hello world! (not send)'); // Will not send a notification

            run(['sleep', '0.1'], notify: true); // Will send a notification
        },
        context: context()->withNotify(false)
    );

    // This will send a notification
    with(
        callback: function () {
            run(['sleep', '0.1']); // Will send a notification
            notify('Hello world! (send with true)'); // Will send a notification

            run(['sleep', '0.1'], notify: false); // Will not send a notification for this specific run
        },
        context: context()->withNotify(true)
    );

    // This will send a notification partially
    with(
        callback: function () {
            run(['sleep', '0.1']); // Will not send a notification
            notify('Hello world! (send with null)'); // Will send a notification

            run(['sleep', '0.1'], notify: true); // Will send a notification for this specific run
        },
        context: context()->withNotify(null)
    );

    // This will send a notification
    with(
        callback: function () {
            run(['sleep', '0.1'], notify: true); // Will send a notification
            notify('Hello world! (send with null)'); // Will send a notification
        },
        context: context()->withNotify(null)
    );
}
