[beatrizmaselli]

What is the purpose of this pull request?

When adding a new address inside my account the user is presented today with a field that is mandatory but the interface point it as optional. Example:

After Change:

What problem is this solving?

This makes the interface more precise and therefore more user-friendly for users.

How should this be manually tested?

Test it here: https://optionaladdress--dunnesstorespreprod.myvtex.com/

Its important not to test in master because in master you have a css currently at the theme to hide the optional text. This was removed at this beta so we can avoid this and have the right native behavior already at the address form: [email protected]
