Subject: [PATCH] fix: use npm v8 in expressapp container to workaround slow
 npm install from github

The switch to node v16 gets use npm v8, to workaround an issue with
slow 'npm install <any github repo dependency>'. See:
    https://github.com/npm/cli/issues/4896

In our case the github repo dependency was the command given to docker
run this container:
    bash -c "npm install elastic-apm-node#SOME-COMMIT-SHA && node app.js"

This also adds a package.json to more explicitly declare we are working
with a node project workspace. Also avoid generating a package-lock file
we won't use.

Fixes: #1483
