[Suggestion] add "Close Account" URLs

As a user of the project I want similar access to the close account link for the site in question, to the change password links that already exist, so that I have an easy time closing my account on a service

Make a file similar to this one:
https://github.com/apple/password-manager-resources/blob/master/quirks/change-password-URLs.json

Proposed file:
https://github.com/apple/password-manager-resources/blob/master/quirks/close-account-URLs.json

Compare the existing quirks/change-password-URLs.json file with the proposed quirks/close-account-URLs.json file. Start by reviewing the linked change-password URL resource and its format. Done means adding the close-account URL resource in the corresponding location and structure, populated with the requested service links.
