Documentation: render special characters correctly

Three hyphens are rendered verbatim, so "--" has to be used to produce a dash. There is no double arrow ("<->" is rendered as "<→"), so a left and right arrow "<-->" have to be combined for that. So fix asciidoc output for special characters. This is similar to fixes in commit de82095a95 (doc hash-function-transition: fix asciidoc output, 2021-02-05).
