Edit Checkout Wording when "Address Prefill" is enabled

When the "Prefill the Shipping address fields with the selected pickup location address" is enabled, the shipping address form will have the address of the selected location in the date picker.

Perhaps the prefilled location address in the checkout page is not that visible because the wording says "Shipping address":

If you would like to modify the “Shipping address” title for your customers in their selected language in your store, you could follow the steps below:

1. Go to your Theme and click on Edit code
2. Click on Locales > Add new locale
3. Duplicate the file: en.default.json (if the language is English)
   1. The first two letters before "default" denote the language. So, in case you need to fix this for other languages, you need to duplicate every file.
4. Add the file name: en-CA
5. Replace the full content of en-CA.json with the following:
