Requisition list Unclear message why there is a problem with the stock

[leonhelmus]

Preconditions and environment

• magento/product-enterprise-edition 2.4.6-p11
• php 8.1
• magento/extension-b2b 1.5.2-p1

Steps to reproduce

When you have a product in your requisition list that only can be bought by the 10 you get the following error from:
\Magento\InventorySales\Model\IsProductSalableForRequestedQtyCondition\IsCorrectQtyCondition::execute:116

Which gives you a nice clear message to the customer on what to do with their requisition list:
You can buy this product only in quantities of %1 at a time.

But when its shown in your customer view and you have for example 51 and you can only buy by the 10 products. you get the following message:
The requested qty is not available

Which does not tell the customer what is wrong and prevent a sale from class:
\Magento\InventoryRequisitionList\Plugin\Model\RequisitionListItem\Validator\StockPlugin::aroundValidate

I used this patch to resolve the issue:

             return $errors;

Expected result

I expect to see the message:
You can buy this product only in quantities of %1 at a time.

Actual result

I see the message:
The requested qty is not available. which prevent a sale from going through.
