Hyperlink DOIs to preferred resolver

[katrinleinweber]

Hello :-)

The DOI Foundation started recommending a new resolver. While their URL change may be a bit ironic, it's now encrypted and the old dx subdomain is being redirected, there is no urgency here.

However, for consistency, this PRs suggests to update all static DOI links accordingly.

Cheers!

If you agree with these update suggestions, how about https://github.com/SPAROntologies/datacite/blob/08ad7785fd34b8f7bc982fb3aae2e98b7dd73dc9/xslt/xml2rdf.xslt#L78-L79 ? Can those be updated as well?

I'm less certain about the parameters in .xslt files: If they are used to generate new DOI links, both can IMHO be updated as above. If they are used to detect DOI URLs, might they need to be duplicated into their https variants?
