Upgrade guide for Grid v7.0.1

Deprecated the event property of Button click and action events

The event property of Button's click and action events has been deprecated and replaced by the domEvent property to better align with naming elsewhere (reducing risk of confusion with Bryntum event objects and Bryntum Scheduler events). It will be removed in a future major release. Replace any usage of it as shown below:

Old code

button.on('click', ({ event }) => {
    // do something with event
});

New code

button.on('click', ({ domEvent }) => {
    // do something with domEvent
});
