add ability to remove protocol from URL

Is your feature request related to a problem? Please describe.

MLA Handbook 8th edition says in 2.5.2 URLs and DOIs:

When giving a URL, copy it in full from your Web browser, but omit http:// or https://.

but modern-language-association.csl can only copy the URL that is given as argument.

see

• https://github.com/citation-style-language/styles/issues/5545
• https://discourse.citationstyles.org/t/new-way-to-specify-unprefixed-urls-in-styles/1731

Describe the solution you’d like

Add an npurl to the list of link renderings:

https://github.com/citation-style-language/documentation/blob/master/specification.rst#appendix-vi-links

that would remove the protocol from a url

For changes to the CSL RNC schemas, this should include links to citation style guides. It’s better to include links to more than one style guide, and no more than five, for us to assess how widely needed this feature might be.

How would that look like?

What I was asking about earlier was a likely a global boolean.

<style url-format="strip-protocol">

I can bang out a proper issue for that if you want and discuss there.

I think we should just remove that part. Maybe a PR?
