Avoid using rawgit.com

[stain]

It has come to our attention (see #394) that the free service https://rawgit.com/ (which re-hosts GitHub files with nicer content-type headers) is shutting down:

RawGit is now in a sunset phase and will soon shut down. It's been a fun five years, but all things must end.

GitHub repositories that served content through RawGit within the last month will continue to be served until at least October of 2019. URLs for other repositories are no longer being served.

If you're currently using RawGit, please stop using it as soon as you can.

https://rawgit.com suggests alternatives like:

• jsDelivr
• GitHub Pages
• CodeSandbox
• unpkg

Here are the redirects I found in w3id.org that uses rawgit.com that should be updated (one example per folder):

• https://w3id.org/akn/ontology/undo.json by @essepuntato
• https://w3id.org/un/ontology/undo.json by @essepuntato @kohsah
• https://w3id.org/bird-a/ by @CaioK
• https://w3id.org/ido/onto.html by @essepuntato
• https://w3id.org/tree/ by @pietercolpaert
• https://w3id.org/library/mwo by @cKlee (uses content-negotiation)
• https://w3id.org/nidash/nidm by @nicholsn
• https://w3id.org/loupe/vocab/ by @nandana
• https://w3id.org/bundle/context by myself (fixed in ro bundle: Avoid rawgit.com as it shutting down #1120)
• https://w3id.org/ro/bagit/profile by myself (fixed in ro bundle: Avoid rawgit.com as it shutting down #1120)

Some of these already fail with:

403 Forbidden
RawGit will soon shut down and is no longer serving new repos. Please visit https://rawgit.com for more details.

.. so I would recommend the authors CC-ed above to update before the October 2019 shutdown date of rawgit.com.

Those who need to update their redirects can check out the jsDelivr automated PR. I'd prefer people confirm their redirects work before we blindly merge that.

Thanks a lot! I changed it to JSDelivr.

[davidlehn]

Huh... The jsdelivr auto-pr got deleted? If those with effected redirects could do their own PRs to update to their preferred service that would be great.

@stain I edited the issue text with some checkboxes so we can track what still needs updating.
