[Serverless]: Assign user roles; update the user roles assignment screenshot

[formgeist]

Serverless Docs

Welcome to Elastic Serverless

Description

I think we can provide a clearer and less visually messy screenshot than the one shown in the docs on this page for assigning roles.

@KOTungseth do you have permissions to our test organization to grab this screenshot that is mentioned in the issue. I only have editor rights and can not see this view for serverless only cloud.

@georgewallace I have access. What exactly do you want to show?

[georgewallace]

@KOTungseth just a cleaner screenshot. You don't have to add Jane Doe to the actual perms but if you can have the name there instead of the blacked out space and a cleaner screenshot that would be fantastic.
