Current Behavior

There is no generator to setup a CI workflow for a Gradle workspace.

Expected Behavior

./nx g ci-workflow sets up a CI workflow for either Github Actions or CircleCI. More will be added later.

Approved

A few questions:

• Do we want to include a GitHub Actions step for installing a particular version of Java?
• Does Circle CI come with Gradle pre-installed? I don't see a setup step for Gradle in the Circle template
