refactor(app-v5): move apps:ps:index to CLI & upgrade to oclif

[zwhitfield3]

Description

Work Item

This command migration used the migrateCommand and migrateCommandTest codmods by @ryandagg & @justinwilaby

This PR also updates the migrateCommandTest codemod write path from a typo bug.

Testing

./bin/dev ps -a heroku-cli-test-staging
./bin/dev ps -a heroku-cli-test-staging web
./bin/dev ps -a heroku-cli-test-staging clock
./bin/dev ps -a heroku-cli-test-staging web clock
./bin/dev ps -a heroku-cli-test-staging --json
./bin/dev ps -a heroku-cli-test-staging --extended

Shutdown any active dynos by running
heroku ps:stop -a heroku-cli-test-staging web.1
heroku ps:stop -a heroku-cli-test-staging clock.1
heroku ps:stop -a heroku-cli-test-staging worker.1

Using heroku ps -a heroku-cli-test-staging, ensure all dynos are in provisioning state

Closing this as I believe we have now converted this command
