SAST support for demo project and CI/CD Template

Job #337941973 failed for 25bcf5ef:

Fixed Problem 1

Helper scripts were causing issues wen prepping the SAST DinD container so I amended the job to skip installing SFDX CLI and other prep steps defined in the before_script portion of the project template's gitlab-ci.yml file.

Problem 2 still broken

For some reason I keep getting this error in the SAST job within the pipeline :

npm install babel-plugin-transform-decorators-legacy --save-dev

and add the following line to your .babelrc file:

{
  "plugins": ["transform-decorators-legacy"]
}

The repo url is: https://github.com/loganfsmyth/babel-plugin-transform-decorators-legacy.

In addition, can't tell if our SAST scan is detecting APEX but it is detecting Node. Maybe it fails before it gets to APEX scanning?
