parseTwig doesn't work to generate SKU when importing Commerce Product

[hassanmah]

Description

I have parseTwig set to true in feed-me.php. When I set SKU to use "Default Value" and set the value to {slug}, the variants SKU is set to the string {slug} and not the slug of the product.

I've seen these two issues in the past for other versions of the plugin. #1035 and #1326

Steps to reproduce

1. Set parseTwig set to true in feed-me.php
2. Set up a feed
3. For SKU, use "Default Value" and set the value to {slug}

Additional info

• Craft version: 5.4.6
• PHP version: PHP 8.3
• Database driver & version: MySQL 8
• Plugins & versions:
  Feedme: 6.4.0
  Commerce: 5.1.3

This should be resolved in Feed Me 5.8.1 and 6.4.1.
