Https-everywhere: pem-jwk and dependency on nodejs can be replaced with a short python script

[pastly]

Type: other

... and a python package not in Debian.

After pip install pyjwkest (possibly in a virtual environment), the following script can replace the need for npm/nodejs in this section on making an update channel

#!/usr/bin/env python3
from jwkest.jwk import RSAKey
print(RSAKey().load('/dev/stdin'))

I realize this is essentially replacing a dependency with a different dependency.

I'm not sure what the current view on this is but it would go against #9993.
