Rule: Update import order rule for all consumers

[benjamincharity]

Updated rule config to output what we used to have with TSLint:

    'import/order': [
      SEVERITY,
      {
        groups: [
          'external',
          'internal',
          'sibling',
          'parent',
          'builtin',
          'index',
        ],
        pathGroups: [
          {
            pattern: '@terminus/**',
            group: 'external',
            position: 'after'
          }
        ],
        'newlines-between': 'always',
      },
    ],
