Only use fallback error messages for non-Spain Spanish

[tillh-stripe]

Summary

This pull request restricts our error message fallback logic to Spanish locales that aren’t Spain itself.

Our backend is unable to provide translated error messages for some language tags. As a solution, we started using client error messages a while ago. However, these error messages aren’t in line with the Web and iOS messages and lack some detail.

Therefore, we now only use the client error messages for the “problematic” languages. As of right now, the only languages for which we are aware of this issue are Spanish languages outside of Spain, such as in Argentina or Chile.

Can we add a test for StripeErrorMapping with different locales?
