cut v1.20.1, patch pt-language provinces to remove superscript markers

[DominiqueFlaaa]

What are you trying to accomplish?

Patch a few Spanish provinces in the PT locale, removing the superscript 2.

This document contains details on the superscript markers, why they are sometimes necessary to distinguish between subdivisions that have identical translated names, and shows a few long term options to fix the problem: cldr-superscript-markers.md
In the case of the Spanish provinces in PT, there are no duplicate translations.

There is no quick fix for all occurrences, so for now I'm addressing this one case on our radar.

What approach did you choose and why?

Added to the existing patches list, re-ran the end-to-end CLDR import.
Verified the changes are present in the pt/subdivisions.yml ✔️

claude init to add a CLAUDE.md

The impact of these changes

This should fix an issue where Spanish provinces in PT are shown with superscript 2.

Checklist

• I have added a CHANGELOG entry for this change (or determined that it isn't needed)

In the case of the Spanish provinces in PT, there are no duplicate translations.

I see duplicates for most of the affected provinces in the pt file 👀 am I interpreting incorrectly? For example:

[DominiqueFlaaa]

Yes, you are right to spot the duplicates! I will revisit the approach

[DominiqueFlaaa]

The unicode data for spain shows the keys for these "duplicate names" are used for different subdivision levels:

Categorizing each duplicate name:

name	code	subdivision level
Navarra	esnc	1
Navarra	esna	2
Cantábria	escb	1
Cantábria	ess	2
Baleares	esib	1
Baleares	espm	2
La Rioja	esri	1
La Rioja	eslo	2

This PR updates the second subdivision level for each, except La Rioja.

When showing the zones of Spain, our systems care about this second subdivision level.

---

I will remove the patch on La Rioja, and focus this change to updating the second subdivision levels of Spain in Portuguese.

[DominiqueFlaaa]

Did not change esri: La Rioja² as this key is for the regional subvidivision (level-1), not the provincial subdivisions (level 2) which are the focus of this patch.
