Some reading on enabling CORS

I found this from a tweet: https://breautek.com/2020/07/14/enabling-cors/

I think this needs to be documented or linked to.

Start by reviewing the linked article on enabling CORS and the Cordova documentation site to find the relevant documentation section. Done means adding a suitable link or documenting the material in the appropriate place, with the resulting page navigation and wording checked.
