Update EXAMPLES.md file: Removal of non-functional sites

[be-next]

Summary

This pull request updates the list of example sites that use Zola by removing entries for sites that are no longer functional. The goal is to ensure that the list remains a reliable resource for users interested in seeing real-world implementations of Zola.

Details

• Checked all sites listed in the EXAMPLES.md file.
• Removed entries for sites that are no longer accessible or have been taken down.
• Verified that the remaining sites still use Zola.

Rationale

Maintaining an accurate and up-to-date list of example sites is helpful for new and existing users of Zola. It provides valuable insights into how Zola can be used and showcases the platform. By removing non-functional sites, we ensure that the list remains relevant and useful.

Testing

Each site was manually visited to confirm its status. Sites that failed to load or indicated a clear departure from using Zola were removed.

Request for Review

I kindly request a review of these changes to ensure that the removal of these sites aligns with the project's goals. Feedback on the criteria used for site removal or additional verification of the listed sites is welcome.

Thank you for considering this update.
