In Store Pickup email still using legacy methods

[smartexcan]

The In Store Pickup "Ready for pickup" notification email still uses deprecated (and removed as of magento 2.4.4) variables with direct method calls.
This results in the affected variables in the email template not being rendered.

See https://developer.adobe.com/commerce/frontend-core/guide/templates/email-migration/

Preconditions (*)

1. Magento 2.4.4

Steps to reproduce (*)

1. Place order with in-store-pickup
2. Send ready for pickup notification email.

Expected result (*)

1. Email with all correct output (store name, customer name, shipping description)

Actual result (*)

1. Customer name is not rendered.
