chore: Upgrade nodejs sdk examples to latest sdk and node

[jake-kramer]

To update yarn.lock files, I applied following patch locally to each dir and ran docker-compose build && docker-compose run --rm us-east yarn install

diff --git a/examples/language-sdk-instrumentation/nodejs/express-ts/docker-compose.yml b/examples/language-sdk-instrumentation/nodejs/express-ts/docker-compose.yml
