Description of Changes

This PR fixes the Portuguese locales values. They should essentially be the same as the Brasilian ones. Also fixed capitalization. We use month name with caps in Portugal.

Thanks.

Hi @pedroma, thank you for the PR. I see that there are similar issues with day_names and day_abbreviations, maybe you can take a look at them as well. The Brazilian locale inherits from the Portuguese locale so there should be no need for duplication for items that are identical.

Hey @systemcatch. No problem. I'll look into it right now.

[pedroma]

Updated the locale. Let me know what you think.

Hey @pedroma sorry I don't see the test?
