[badrivlog]

Fixes Issue

closes #10138

Changes proposed

• Add getUserAvatar function for generating user avatar URLs
• Created a versatile Avatar component that can be utilized throughout the project where user avatars are displayed. The component supports customization options such as size, radius, borders, and link integration for enhanced flexibility and consistency
• Introduced a new AvatarGroup component to efficiently display groups of avatars with the option to truncate and show more items. This component allows customization of avatar size, border, and border color for each item in the group. It enhances code reusability and provides a flexible solution for avatar display within various contexts across the project
• Implemented the UserAvatarGroup component to efficiently display avatars of multiple users. This component utilizes the AvatarGroup component internally, providing a convenient way to display user avatars fetched from GitHub using the getUserAvatar function. Each avatar is associated with the user's username, profile picture, and a link to their profile page
• avatarize community repos contributor in the repos page

Step to test

Test Rendering of AvatarGroup: To create a simple test case to render the UserAvatarGroup component and see if it renders without any errors 1.

 // Please use the following list of GitHub usernames for testing purposes:
const TEST_GITHUB_USERNAMES = [
  "eddiejaoude",
  "sarajaoude",
  "amandamartin-dev",
  "pradumnasaraf",
  "dan-mba",
  "chinmaymhatre",
  "kumarsonsoff3",
  "sital002",
  "badrivlog",
];

// Replace the `users` prop with the following code when mapping through users:
<AvatarGroup
 itemsSize={20}
 borderedItems
- items={users.map((username) => ({
+ items={TEST_GITHUB_USERNAMES.map((username) => ({
   id: username,
   username,
   image: getUserAvatar(username),
   alt: `Profile picture of ${username}`,
   href: `/${username}`,
 }))}
/>

2. go to localhost:3000/repos
3. ensure that the component renders the avatars correctly with the provided test usernames.
4. verify that clicking on each avatar navigates to the correct user profile.
