Bumping Node version and fixing Github Actions failures

[JohnAllenTech]

Pull Request details

• This is a first step in fixing the broken github action pipelines.
• Currently there is a duplicate devDependencies key in the package.json. This is causing only 'gulp-uglify-es' to be installed when you run yarn
• I have also bumped the Node versions to be tested against from 9,10,12 to 12,14,16
• Bumped the node version for the other pipeline steps to 16

*** This PR may not fix the pipelines but will give me enough information to get a fix together. Currently the pipelines dont even get past the test step ***

Any Breaking changes

• The opposite. The pipelines are currently broken and this is a first step to a fix
