[Bug]: fix examples projects lockfiles warning

Running npm install in the examples directory changes the lockfile since the old lockfile is not supported anymore.

There are warnings about deprecated libraries used as well as security vulnerabilities in locked dependencies.

Relevant npm install output in simple/

Lockfiles & critical vulnerabilities are fixed.

Some moderate vulnerabilities remain, but we can't fully solve them without replacing karma with a new test runner. I'm not sure how complex that task is, but we're looking into it.
