fix(compliance): updated the npm packages

Updated the outdated npm packages. All the tests are running with success.

Only one dev dependency is pending for update is `readable-stream`

```console
Package          Current  Wanted  Latest  Location
readable-stream    2.0.6   2.0.6   3.1.1  soap
```

I am not sure exactly why this package is used in tests and looks like there
will be some changes needed if we update the package.
