fix: issue-698 author link not working in quote post

[igor-baiborodine]

Issue

This PR addresses issue #698, where author links in quote posts were not working correctly. Previously, the author's name was being automatically converted to a link that pointed to an author page using a pattern like /author/author-name, which wasn't functioning as expected.

Changes

• Added an optional quoteAuthorLink parameter to quote posts to explicitly define where the author name should link to
• Updated the quote template to use the provided quoteAuthorLink when available
• Added the quoteAuthor and quoteAuthorLink fields to the quote archetype for new quote posts
• Updated example quote posts with appropriate external links to demonstrate proper usage

Benefits

• Authors of quotes can now be properly linked to external resources (like Wikipedia pages)
• Improves overall user experience by providing working links for quote attributions
• Maintains backward compatibility as existing quotes without the authorLink parameter will simply display the author name without a link

Testing

The changes have been tested with the example site to confirm proper functioning of the new authorLink parameter.
