Fix: skip empty wp:docPr descr/title attributes for Word 2007 compatibility

Description

This pull request addresses an issue where empty descr="" and title="" attributes were being generated inside <wp:docPr> nodes for image runs. These empty attributes can cause parsing issues in Microsoft Word 2007, which doesn't handle them properly, sometimes leading to rendering errors or failure to open the document.

What’s Changed

• Updated the logic in DocProperties to skip the inclusion of description (descr) and title attributes when they are empty, null, or undefined.
• This update ensures that only non-empty values for description and title are included in the generated XML.
• The fix improves backward compatibility with Microsoft Word 2007 and similar older versions, which had issues with empty attribute values.

Example: XML Output Before and After

Before (current behavior):

<wp:docPr id="1" name="ExampleImage" descr="" title=""/>

After (with this PR):

<wp:docPr id="1" name="ExampleImage"/>
