Try to fix null email address

🩹 Fixes

• Use .id+.login when pusher.email is null

🏗️ Improvements

• Replace curl w/ gh api

💔 Broken

• act v0.2.23 and below will not work
• act v0.2.24+ could work if your base image includes gh -- you can manually install gh before using this (fixed in the v0.0.4)
