github PR security scans fail due to node-gyp usage of deprecated python features with base image that includes Python 3.11+

Dependency on node-sass -> node-gyp should be brought up to at least node-gyp 8.4, which includes changed code for newer python which does not attempt to open with "U" mode.

Change to fix node-gyp: https://github.com/nodejs/node-gyp/commit/c3c510d89ede3a747eb679a49254052344ed8bc3
