downgrade rimraf to @^4.x for downstream builds

Downstream builds use an npmjs package caching system called
cachito[1].  It currently does not support dependencies that use
a package-spec alias[2][3].  Downgrading `rimraf` to version `^4.x`
removed any aliases from our `package-lock.json` and should allow
downstream builds to work again.
