Editorial: For better accessibility, name all hyperlinks

[gibson042]

As discussed at tc39/ecmarkup#588 (comment)

...but if there is desire to keep any visible URLs in screen presentation, I would like to mark such hyperlinks with a "print-ready" class and update ecmarkup to accommodate them with pure CSS as suggested at tc39/ecmarkup#588 (comment) :

+/* Render non-mailto external link targets, cf. https://url.spec.whatwg.org/#special-scheme */
-a[data-print-href]::after {
+a:not(.print-ready):is([href^='ftp:' i], [href^='sftp:' i], [href^='http:' i], [href^='https:' i], [href^='ws:' i], [href^='wss:' i])::after {
   content: ' <' attr(href) '>';
   color: initial;
 }

Some of these links are better named, but in all media, i think most of them are better with visible URLs.

@gibson042 If you want to talk about this with us on the editor call tomorrow, you're welcome to attend.

At editor call today, we agreed that it is a non-goal to remove all links that display as the URL from the document. We will, however, review each replacement in this PR and determine their suitability individually.

We will, however, review each replacement in this PR and determine their suitability individually.

Reviewing the commits individually should support that plan.
