Node Version Update / Server Dockerfile

[RR-Helpdesk]

Build stops at Lighthouse Step 15 with Node v12. I updated the Dockerfile to pull Node v14 and was able to proceed, but may need to update your dependencies here.

Hello @REVREBEL , thanks for the update :)
Could you do a PR with your update ?

Hello I was having the same issue so I just bumped the node version in the dockerfile. Figured I'd make a pull request.
