Improve output of command examples

[grof]

Not completely sure, but it seems that when we upgraded to the more recent version of oclif, the output of command examples started showing "double spaced". I believe we had manually spaced the examples back in the day and now they appear with extra blank lines.

EXAMPLES
  Create an application configuration using latest builds from project without data hosts information

  $ mix app-configs:create -M 233 -D 32 -T AC_20211028 -P 1922



  Create an application configuration using latest builds from project but only for build type ASR

  and locale en-US, without data hosts information

  $ mix app-configs:create -M 233 -D 32 -T AC_20211028 -P 1922 --with-locale en-US --with-build-type asr



  Create an application configuration using latest builds from project including data hosts defined in project

  $ mix app-configs:create -M 233 -D 32 -T AC_20211028 -P 1922 --use-project-data-hosts
