CI Should Have Better Error Output Format

Right now we output all of our error output in our assert string.

We could add new lines between the returned `parameters` and `template` response object which shows the actual rendered parameters and template file contents used. (for example it will show what GEN-UNIQUE-12 was replaced with).

We can also colorize the output to highlight the important parts. There's a [nice npm package that does this](https://www.npmjs.com/package/cli-color)

No files or tests are named. Start by locating the CI code that assembles the assert string and inspect how the returned parameters and template response are produced. Use a case involving GEN-UNIQUE-12 to compare the current output with the intended separated, colorized format, using cli-color as the referenced package.
