For alerts, add default vocalisation on "info" status

[pya35]

Prerequisites

What happened?

For alert components, "warning" and "error" status are correctly vocalised with screen reader. But "info" status should also be vocalized "information" as it can be useful for the user.

I have no idea about others status "positive", "neutral", "accent" and "positive", by default no label but maybe optional, depending on context?
