Retrieves path of category template in current or parent template.

The hierarchy for this template looks like:

1. category-{slug}.php
2. category-{id}.php
3. category.php

An example of this is:

1. category-news.php
2. category-2.php
3. category.php

The template hierarchy and template path are filterable via the {@see ‘$type_template_hierarchy’}
and {@see ‘$type_template’} dynamic hooks, where `$type` is ‘category’.

function get_category_template() {
	$category = get_queried_object();

	$templates = array();

	if ( ! empty( $category->slug ) ) {

		$slug_decoded = urldecode( $category->slug );
		if ( $slug_decoded !== $category->slug ) {
			$templates[] = "category-{$slug_decoded}.php";
		}

		$templates[] = "category-{$category->slug}.php";
		$templates[] = "category-{$category->term_id}.php";
	}
	$templates[] = 'category.php';

	return get_query_template( 'category', $templates );
}
