ci: remove dependency on semantic-release npm

[MikeMcC399]

• relates to issue Script tests for other ESLint versions give warnings or fail #163

Issue

• Using the following test scripts in CircleCI results in failure if the npm module semantic-release is updated (see failure in PR fix(deps): update semantic-release to 19.0.3 #162):

• "test:v4": "npm i [email protected] && npm run test"

• "test:v6": "npm i [email protected] && npm run test"

This combination is causing an incompatible version of npm to be used. This problematic npm version is provided through the npm module semantic-release.

Changes

1. Convert calls from npm install to npm ci.

   npm ci was released with [email protected] in Feb 2018

2. Make installation and test of alternate versions into two separate steps.
