docs: Don't confuse asciidoc with asciidoctor

Apparently, asciidoc and asciidoctor are two different
projects. nvme-cli depends on the former. Depend on asciidoc only and
make it a hard dependency when the user ask to build the doc.

Fixes: 6b18babf40d4 ("docs: Search for 'asciidoctor' as alternative")
