klish-plugin-infix: restore missing CLI commands moved to show context

Some CLI commands where inadvertently moved from the global CLI
context into the show context.

For example the upgrade command.

As a result, commands like upgrade were unavailable at the top-level
prompt:admin@ix-00-00-00:/> upgrade ?
Error: Command not found, or incomplete.

However, these commands remained accessible under the "show" context
as a temporary workaround:

admin@ix-00-00-00:/> show upgrade ?
URI  [(ftp|tftp|http|https|ftp)://(dns.name | ip.address)/path/to/]upgrade-bundle.pkg

This patch restores the affected commands to the global CLI context so
that commands like upgrade function as intended at the root prompt.
