goldmark Typographer issues

Note, 2022-02-28: Thanks to code contributed by Nate Moore, goldmark v.1.4.7 resolved these problems; Hugo 0.93.0 was the first Hugo release to include that goldmark version.

Here are examples of issues found with the Typographer extension in the goldmark Markdown parser, which Hugo uses. I hope this will help @yuin and PR-submitters resolve them; see this comment.
Repo for this site: https://github.com/brycewray/gm-typographer.

For each issue, you’ll see:

• The Markdown
