feat(replay): Capture keyboard presses for special characters

[mydea]

This adds a new breadcrumb for keyboard presses of special characters.

It creates a breadcrumb like this:

{
    category: 'ui.keyDown',
    message: 'body > div', // same as for clicks
    data: {
      // node stuff same as for clicks, plus
      altKey: false,
      ctrlKey: true,
      key: 'Escape',
      metaKey: false,
      shiftKey: false,
    },
    message: 'body',
    timestamp: expect.any(Number),
    type: 'default',
}

We do not capture this when:

• target is input or textarea
• typed key is only a single character without ctrl/alt/meta modifier

This way, we should hopefully only capture key combinations & special stuff, not when users are typing.

Closes #6532 (comment)

for initial data collection this seems reasonable. we can look for chords on the backend and see how common that is.

The way things are setup on the UI: These new categories will render in the breadcrumb list under the player. It'll have the title User keyDown
