`azure-pipelines-tasks`: refactor to use github cdn do fetch prepared data

[viceice]

What would you like Renovate to be able to do?

Currently we've need to update a very big json file to get new datasource data. We should instead provide that in a seperate repo and renovate should fetch it on demand, like and other datasource.

• https://github.com/renovatebot/azure-devops-marketplace/issues/4

If you have any ideas on how this should be implemented, please tell us here.

• Remove json files
• host prepared json files inside https://github.com/renovatebot/azure-devops-marketplace
• fetch files on demand

Is this a feature you are interested in implementing yourself?

Maybe

@JamieMagee Can you look at the fetching the JS bits of this work? I've generated the json data on a branch in the other repo. I don't trust myself with the networking code just yet.

[JamieMagee]

Yep, can do.
