Issue-8: Update build v3 (#13)

build and deploy should be in same file

Received the following error during build:

`The workflow is not valid. .github/workflows/deploy.yml
  (Line: 21, Col: 3): The workflow must contain at least
  one job with no dependencies.
`

The easiest way to resolve this is to move the
deployment back to the same workflow file as the build.

Relates to Issue #8
