[FIX] l10n_pe: add zip to Peru address format

Steps to reproduce the bug:
- Install eCommerce and l10n_pe
- Go as website visitor
- Add anything to your cart
- Continue with checkout to go to the address page
- Select country Peru and fill in all the required fields
- Validate
- You will get an error message telling you that you forgot to fill in a required field.

Problem:
You cannot validate the address because zip code is not displayed, but required.
This field is based on the country format address to be displayed before or after the `" City "` field
and is not displayed if `" zip "` is not present in the country format address.

Solution:
"zip" is required for the Peru country, so it must be added in the address format
