Summary of Changes

This PR fixes the duplicate URL issue between Tagged Items menu and Popular Tags module. The fix removes the unnecessary ?types[0]=1 parameter from the URL when a "Tagged Items" menu item is configured to display only "Articles" content type.

Technical change:

• Modified components/com_tags/router.php (Joomla 4) / components/com_tags/src/Service/Router.php (Joomla 5)
• Added condition to remove types parameter when it contains only value 1 (articles)
• Prevents the parameter from being added to SEF URLs

Testing Instructions

Prerequisites:

1. Create a tag (e.g., "test-tag")
2. Create 2-3 articles and assign them to "test-tag"
3. Enable/Publish the "Popular Tags" module

Test Setup:

1. Create a menu item: Tags → Tagged Items
2. Select "test-tag" as the tag
3. Under "Content Type Options", set "Select Content Type" to "Article" only
4. Save the menu item

Before applying this PR:

1. Click the menu item → URL contains ?types[0]=1 parameter
2. Click the same tag from Popular Tags module → Clean URL (no parameter)
3. Both URLs show same content (DUPLICATE CONTENT ISSUE)

After applying this PR:

1. Clear Joomla cache (System → Clear Cache)
2. Click the menu item → Clean URL (no ?types[0]=1 parameter)
3. Click the same tag from Popular Tags module → Same clean URL
4. Both URLs now match (ISSUE RESOLVED)
