Fix #10372 - Product import fails with fatal error

[simonr44]

Description

When importing products via CSV file on a server running PHP 8.2 the following error is thrown when reaching the product prices within the import.

PHP Fatal error: Uncaught TypeError: mb_substr(): Argument #3 ($length) must be of type ?int, string given in /var/www/include/utils.php:5149

This is caused by the price vardefs which are in the format 26,4 with 26 representing the overall length and 4 representing the potential decimals.

In PHP8.2 this throws a fatal error and prevents the import from completing.

Issue: #10372

Motivation and Context

When importing products, the import fails with no errors displayed through the UI, just an empty warning box.

How To Test This

• Prepare an import CSV with the required fields and at least one price
• Import the CSV
• The import will fail and the 500 fatal error logged

Types of changes
