Update check-cla action

[kenodegard]

Description

A few maintenance improvements:

• converts metadata step (previously JS code) into GitHub Action Expressions
• converts add signee step (previously JS code) into Python script
• updates default input values based on upcoming move from conda/infrastructure to conda/cla

Depends on #203

Questions

• Do we really need to be setting a cla-signed [bot] added once the contributor has signed the CLA label? It's the CLA check status that's actually being used to verify if a contributor has signed the CLA so is the cla-signed [bot] added once the contributor has signed the CLA label just noise?

Looking good!
