Pretty sure the man page is not generated for a reason.

So the man pages were being copied from the upstream release, I had a discussion with @ahesford & I think @classabbyamp on IRC before my v4.13.2 update PR (#59546) about it and they suggested to generate it during the build process itself by using the ruby-asciidoctor if $CHROOT_READY, since adding perl and enabling documentation flag did the work, I kept it this way. Are you suggeting to keep the man page generation the way it was before or should I go with using the $CHROOT_READY check?

Reverted changes to man page generation
