feat: Build list of included ISO country codes

[camdecoster]

Description

Update topojson build script to generate a list of ISO country codes.

Closes #7621.

Changes

• Update build script
• Update info related to disputed territories

Testing

• Be on this branch
• In a terminal, cd into the topojson folder
• Run npm run build (this could take a bit to download the required files)
• Check the resulting list in the dist folder and make sure it includes the name and ISO code
• Open the countries map (topojson/build/geojson/un_geodata_simplified_50m/countries.geojson) in Mapshaper and run the following command in the console: -filter '["XBT", "XHT", "XAC", "XAP", "XIT"].includes(iso3cd)'
• Verify that there are 5 polygons and that they include the following disputed territories:
  • Ilemi Triangle
  • Halaib Triangle
  • Bir Tawil
  • Aksai Chin
  • Arunachal Pradesh

Notes

• Since the maps are being updated, these will need to be included in the next plotly.js release

TODO

• Add draftlog

@camdecoster What is the impact of this change? (Could you open an issue? 😉 )

[camdecoster]

I created #7621 but forgot to add it to the OP. I updated it.

@camdecoster This has no impact on the library itself, correct?

[camdecoster]

That's correct. The impact will come when we include the new maps in the next release.
