[API] Generated Package URLs should be included in the API

[adriens]

❔ About

Currently, there are a lot of useful data about Product identifiers :

And the clickable links are really very useful, but (except for repology), the url is not provided by API : it's "only" produced for the web render by the templating : _plugins/identifier-to-url.rb#L34

💡 The idea

Provding the target url as part of the API would be really very interesting so API clients would not have to reimplement the logic on the client side.
