Use two decimal places for LAK

[tillh-stripe]

Summary

This pull request fixes an issue where the Laotian Kip was formatted incorrectly.

To fix this, I added LAK to the special cases in CurrencyFormatter and also made PayWithGoogleUtils use that class to determine the amount of decimal places. This makes sure that PaymentSheet and Google Pay display the same values.

Changelog

Thanks! Let's add a test an ship it!

[tillh-stripe]

Yep, was planning on adding it (and just did)!

[porter-stripe]

I think this is worth mentioning in the changelog!

[tillh-stripe]

@porter-stripe Yes, added it to the changelog already. I’m just looking into aligning Google Pay with this change, because we continue to display the incorrect amount there.
