Customizable receipt path

Problem/Motivation

Currently, there is no way for a customer to view a receipt under a non-admin path, as specified in https://www.drupal.org/project/commerce_view_receipt/issues/3453363

Beyond that I would like for this path to be customizable.

Proposed resolution

Either have a configuration option within the module to change the path to the receipt and/or expose the receipt entity to pathauto and let pathauto handle applying the alias patterns.
