Fix: Term Description block skips display filters inside Terms Query.

[jorgefilipecosta]

When the Term Description block renders inside a Terms Query loop, it outputs the raw $term->description value, skipping the term_description display filters. Multi-paragraph descriptions lose their paragraph tags and collapse into a single run of text, and any formatting plugins add through the filters is ignored. The same block on a taxonomy archive template renders correctly, because that path goes through term_description().

This PR fixes the issue by retrieving the value with get_term_field( 'description', $term ), which applies the same display filters as the archive path, so both contexts render identically.

Testing Instructions

1. Create a category and give it a description with two paragraphs.
2. Add a Terms Query block to a page and keep a Term Description block inside the Term Template.
3. View the page on the front end and verify the description keeps its paragraphs, matching how it renders on the category archive.
