Need explicit guidance for creating content for messages (error, information, warning).

Hey, Scott, Lauren, and Anna. Here's most of our feedback for the Notification component, which we want to go through with you and other CDSers on Tuesday.

We're also wondering about the error, warning, info, success statuses. We're sure why that's mentioned in the
pattern but not in the Usage tab of this component.

@lesnider would you humor me and re-submit this request using this form? I'm curious if it will help us with the triage process.

@sstrubberg Hey, Scott. How does this look? #4238

@sstrubberg @alina-jacob I was told to hold off on making content changes to the Notification component topic because it was under construction. May I proceed now, please?

[laurenmrice]

@lesnider The new content for Notification is still currently in a couple different PRs and has not merged into our live website yet, so I would still hold off on making any new changes to the content until those PRs are merged. We will reach out to you once Notification can be worked on. Thanks!

[laurenmrice]

@lesnider The PRs on our side are merged and the Notifications Usage tab is up to date on the website. This is available to be worked on now.

I also noticed there is another issue open with this same name here: #4238. Do these need to be separate issues, or can we combine them into one?
