ACAS-762 pin npm to get fix for too many connections issue

[bffrost]

Description

The issue with our builds (ACAS-762) appears to be caused by this npm issue npm/cli#7072 . That issue has been fixed in a new release of npm, but Node hasn't yet made a release. To get our builds unstuck I'd like to pin npm.

How Has This Been Tested?

• Ran an arm build on my mac and confirmed the ACAS image is able to run and successfully starts up node
• Tried running a multi-arch build on my mac docker buildx build --platform=linux/arm64,linux/amd64 . but this got stuck and eventually I cancelled it (after ~8 hours) with this error:

=> [linux/amd64 11/19] RUN     npm install -g [email protected] [email protected] [email protected]                       329.3s
 => => # npm WARN deprecated [email protected]: Chokidar 2 does not receive security updates since 2019. Upgrade to chokid

The real test will be running in our CI environment on GH actions.
