Add build:test-project to CI along with additional commands

[thedavidprice]

The idea here is to round out my release QA process in CI:

• build and test the build:test-project with every PR
• use the build project to test CLI commands not yet included in CI

ToDo:

• Matrix run on Linux and Windows; Node.js v14 and v16
• include all commands from E2E + QA commands
• Possibly use Playwright to manage yarn rw dev and yarn rw serve
• add necesary options to yarn build:test-project

@thedavidprice If yarn build:test-project was failing for you, there's a fix for it in my PR here: d9a0c70.

@thedavidprice once you do this, maybe we can simply the test project creation so that we just copy files across rather than use jscodeshift or run generate commands?

[thedavidprice]

@dac09 OH, this just gave me an idea... will work on it within this PR and show you that way.

🤞
