docs: Add a link to installer flag docs from backup instructions.

The documentation for restoring backups referenced that it needed to
be to the same version of PostgreSQL, but did not explain how to do
that.

Link to the relevant section of the installer documentation, and name
the flag explicitly.

Fixes: #23691
