update `pubmed` redirect pattern

[VladimirAlexiev]

https://registry.identifiers.org/registry/pubmed shows the redirect pattern https://www.ncbi.nlm.nih.gov/pubmed/{$id}.
However, the current pattern is https://pubmed.ncbi.nlm.nih.gov/pubmed/{$id}/ (pubmed not www; and trailing slash), as you can check with:

curl -IL https://identifiers.org/pubmed:16333295
HTTP/1.1 302 Found
Location: https://www.ncbi.nlm.nih.gov/pubmed/16333295
HTTP/1.1 301 Moved Permanently
Location: https://pubmed.ncbi.nlm.nih.gov/16333295/

Please update the redirect pattern to avoid the need for double redirect.

Perhaps https://github.com/identifiers-org/cmd-iaso redirection-chain analysis can find all such cases?

Thank you for letting us know of the issue. I updated the pattern.

Unfortunately, we are currently not running iaso periodically. The project has been unmaintened for a while and we are considering to work on a alternative more in line with the tech stack used by the other identifiers.org services. If you or anyone would like to contribute to iaso, we could discuss it.
