"""Update :origin:`searx/data/external_bangs.json` using the duckduckgo bangs
(:origin:`CI Update data ... <.github/workflows/data-update.yml>`).
from :py:obj:`BANGS_URL`.
https://duckduckgo.com/newbang loads:
* a javascript which provides the bang version ( https://duckduckgo.com/bv1.js )
* a JSON file which contains the bangs ( https://duckduckgo.com/bang.v260.js for example )
This script loads the javascript, then the bangs.
The javascript URL may change in the future ( for example
https://duckduckgo.com/bv2.js ), but most probably it will requires to update
