feat: Introducing avatar tooltip

[canerakdas]

Description

I saw it in Slack (OpenJS Foundation) threads and thought it was a good way to support contributors

With this PR, the Tooltip component was created and minor refactors were made to Avatar and AvatarGroup components. In addition, the WithAvatarGroup component was created to make avatars easier to manage to simplify the process

I took care to use the elements/components in the existing design system as a design, I was inspired by (Search typing) in the Figma for the Tooltip component;

Validation

• Avatars should continue to work as it is.
• A tooltip should appear for users in authors.json whose website field is exist
