Custom “Featured Image” Tag Not Working As Expected

[jgorin-playeasy]

Issue Title: Custom “Featured Image” Tag Not Working Properly

Description: When using the custom tag for “Featured image” during post imports, the specified custom value is not utilized. Instead, the placeholder [#item_image] is always used as the featured image. This unexpected behavior does not allow using custom paths for featured images.

Steps to Reproduce:

Configure the feedzy-rss-feeds plugin to import posts.
Add a custom tag for “Featured image” in the feed settings.
Import a post with a custom image URL based on the specified custom tag.
Observe that the custom value is not used, and [#item_image] is used for the featured image.
Expected Behavior: The plugin should correctly utilize the custom value provided for the “Featured image” tag during post imports.

Potential code issue:

feedzy-rss-feeds/includes/admin/feedzy-rss-feeds-import.php

Line 1762 in eced321

$default_img_tag = ! empty( $import_featured_img ) ? '[#item_image]' : '';

When changing the above line to
$default_img_tag = ! empty( $import_featured_img ) ? $import_featured_img : '';

The correct custom image path is used instead of [#item_image]
