help: fix invalid debugupgraderepo commands after reflow

Mercurial recently got some new cases where a user might end up with
repositories that can't be handled by older Mercurial versions or by a
Mercurial without rust extensions.

Some help for these cases was added in 6d79894d3460 and 5e7a0348acf8. The help
text source contains `hg` commands with `\` escape at end of line. They were
however not marked up correctly as pre-formatted and would be line-wrapped and
suggest invalid commands.

Fixed by proper RST markup with `::` and indentation.
