Add `dismissible` option to `Alert` component
Created by: lrhacker
To help ensure we adhere to a standardized design pattern for dismissible alerts, it'd be better to have dismissible
as part of the Alert
component API (rather than relying on consumers to pick their own button/icon/text to use for dismissal). It may look something like:
<Alert dismissible={true} onDismiss={() => {}}>
Something you can dismiss
</Alert>
Final design for the dismissible Alert UI is still TBD. See this Slack thread for more context.
