fix: replace deploy steps to run

[kelvintaywl]

Checklist

Updates deploy steps to use run instead.

Resolves #128

I was able to verify that compiled Orb is valid:

$ circleci orb process src/@orb.yml > orb.yml
$ circleci orb validate orb.yml
Orb at `orb.yml` is valid.

I checked that the update-description command is also tested under the publish-docker-update-description test case.

example: https://app.circleci.com/pipelines/github/CircleCI-Public/docker-orb/796/workflows/92fbd710-d32d-492a-b4e0-79362afef857/jobs/13674

• All new jobs, commands, executors, parameters have descriptions
• Examples have been added for any significant new features
• README has been updated, if necessary

Motivation, issues

The PR is looking good but the review step is failing because the push.sh file was never imported into the command. I'll push the fix and after squashing it, this PR should be good to be merged.
