doc: remove asciidoctor hack

Commit Message

Felipe Contreras April 24, 2023, 2:51 p.m. UTC

The hack was added in 7a30134358 (asciidoctor-extensions: provide
`<refmiscinfo/>`, 2019-09-16) in order to deal with the fact that
asciidoctor doesn't pick up `manversion`, however, we don't require
`manversion` anymore, since 9a09ed3229 (doc: simplify man version,
2023-04-07).

So we can get rid of this hack without any functional changes.

The caveat is that we now require asciidoctor v1.5.7, which was released
5 years ago.
