Holidays data provider

[rodrigouroz]

Consider migrating to https://github.com/commenthol/date-holidays

Pros:

• Faster, local responses

Cons:

• Need to investigate a way of building the app when this package is updated. Perhaps using github actions with a cron?

An idea could be to trigger a deploy (https://vercel.com/docs/more/deploy-hooks) from a scheduled github action that checks once month and if the date-holidays package was updated, it triggers a deploy from master.

The current provider lacks several countries (Israel, India to name a few).
