Option to clear VueAnnouncer after a delay

[gcamacho079]

While testing VueAnnouncer in our application, I noticed that the contents of VueAnnouncer aren’t cleared out, so a user can find outdated status messages while navigating through the page.

Including an option to clear the live region after a delay might be nice. This could help in instances when:

• The live region is visually-hidden, and we don’t want users to stumble upon outdated update messages.
• An identical message is injected in the live region, but it isn’t announced because the text string hasn’t changed

Thanks in advance!
