🔥 chore (AMP): Drop amp-addthis extension and components

[chriskyfung]

Description

The amp-addthis extension is no longer maintained and has been deprecated. It is recommended to drop this extension and its associated components from the codebase for the following reasons:

• Maintenance Burdens: The extension is no longer actively maintained, which can lead to technical issues and security vulnerabilities.
• Performance Impact: The extension can introduce performance overhead to AMP pages, which can negatively impact user experience.
• Lack of Support: The extension is not supported by any major AMP framework or library, making it difficult to integrate and debug.

Proposed Changes

• Remove the amp-addthis configuration from the Jekyll theme's _config.yml file.
• Delete all references to the extension and its components from the theme's codebase.
• Update the theme's documentation to reflect the removal of this extension.

Benefits

• Improved performance and reliability of AMP pages.
• Reduced maintenance burden.
• Simplified codebase and improved extensibility.

Timeline

This change should be implemented within the next release of the Jekyll theme.

Additional Notes

• Users who rely on the amp-addthis extension will need to find alternative methods for adding social sharing buttons to their AMP pages.
• There are several other AMP-compatible social sharing extensions available, such as AMP-Social-Share and AMP-Story-Sharing.
• Please provide feedback and suggestions on this proposed change.
