fix(aws-lambda): updated brace-expansion in icr.io/instana/aws-lambda-nodejs image (#1944)

refs https://jsw.ibm.com/browse/INSTA-48333

- node & npm is installed from this image: public.ecr.aws
- it can contain old subdependencies of npm
- ensure we always update npm to latest version (this will also update sub deps)
