Description

This pull request introduces a new feature that enables users to repost articles from external sources while ensuring proper attribution to the original content creators. The implementation enhances the post layout to conditionally display original author information and source links when an article is reposted.

Key changes include:

• Addition of new front matter variables: original_url, original_author, and original_source to capture attribution metadata
• Modification of the post layout template to render a dedicated attribution section for reposted content, clearly distinguishing it from original posts
• Inclusion of new localization strings across all 33 supported languages to maintain consistent and accurate attribution messaging in every language
• Updates to example post documentation to illustrate correct usage of the new front matter variables

This feature ensures that reposted content maintains integrity and proper credit to original authors and publications, aligning with best practices for content sharing and attribution.
