Update engines in package.json to only allow Node version 14.x.x.

**Describe the bug:**

When using node version 16 LTS, errors related to not finding correct packages are reported when running `npm install`. While updating these packages may resolve these issues, the simpler solution is to ensure the developer is using the current available

**Resolution:**

Update engine configuration in package.json to only allow Node 14.x.x. (until we have a fix for Node 14+)
