Fix npm version compatibility & depreciation msg

[Loki-101]

The latest version of NPM for NodeJS 17 going off https://nodejs.org/en/download/releases is 8.11.0. Leaving it as @latest results in the following error during build:

=> ERROR [3/5] RUN npm install npm@latest--location=global 0.9s

[3/5] RUN npm install npm@latest--location=global:

ERROR: failed to solve: process "/bin/sh -c npm install npm@latest--location=global" did not complete successfully: exit code: 1

Additionally, there was a message during build about -g being depreciated and using --location=global instead, so I figured as long as I'm making a change to this anyways I may as well switch that out. With the first change it builds successfully, with the second change it builds successfully without the depreciation message.

It looks like the other images also have npm@latest, but are building successfully. Not sure why this one is different.

Danny figured out why @latest no longer works for this build: npm/statusboard#519
Node no longer supports version 17, so the engine stopped supporting it. The other old versions still work because even versions are more stable; support hasn't been dropped for them.
