chore(cli-integ): node-gyp fails on newer python versions (#407)

The `cli-integ` tests depend on the `node-pty` package for testing of
interactive terminals. This package needs to be build at install time
using `node-gyp`. Because previously `cli-integ` tests dependet on an
old version of `npm`, we got an old version of `node-gyp` which is
incomaptible with recent python versions.

To fix this, we upgrade the dependency to a more recent version of
`npm`.

Fixes failing Python package release.

Proof this fix works:
