fix: allow skus with ':'s

[adamzero1]

Description (*)

When running bin/magento inventory:reservation:create-compensations if the sku contains ':' the regex breaks, and then the entities can't be loaded.

Fixed Issues (if relevant)

Manual testing scenarios (*)

This is difficult as it requires you to have a reservation inconsistency for a product with a sku with a ';' in it. But if this is the case simply run:
php bin/magento inventory:reservation:create-compensations
(with the compensation string)
You will get error like: "Get EntityId on null"
