Build failed with error code: 1

Environment Which version of LinuxForHealth FHIR Server?

To Reproduce Steps to reproduce the behavior:

1. make a change to the docs
2. merge the change into master

note the build failure

Expected behavior docs site should update on each commit that includes a change to docs

Additional context Previously we were getting errors related to our outdated Node.js. I think these errors started after I tried bumping that version to a LTS release. Needs investigation.

Tried adding .npmrc file in the project folder containing python = "/usr/bin/python2.7" but still seeing the same error as above. The common suggestion to fix the above error is to update the node-sass version which supports node 18 as mentioned in below link. https://www.npmjs.com/package/node-sass
