Latest pem works with openssl 3 but is not released for 8 months. Using directly git repo for npm.

See Dexus/pem#316

I would recommend to avoid using the git reference to the pem repo and just merge it even though the ci pipeline fails.

Replaced pem with self-cert in #72.

So first we merge #72 and then we merge master into this branch, and then it should be good ;)
