feat(Alert): add custom role, status or alert

[iNeoO]

#438

@iNeoO Even with this patch it looks like we cannot render an uncontrolled Alert (without passing a prop isClosed) with a custom role. Even in controlled mode it seems like the role is only set when the Alert transitions to closed. Am I missing something with the usage of this component?

Hi, shouldn t have probleme, can you provide an exemple of your usage ?

Here's a reproduction: https://codesandbox.io/p/sandbox/reverent-worker-75w3gp?file=%2Fsrc%2FApp.js%3A8%2C27

Even if i set the role prop, it is not defined on the DOM node.
