Usage: $0 <version> [--no-push] [--no-package]

Creates a reproducible Plugin Builder pre-release candidate:
  1. validates master and a clean worktree
  2. updates $projectFile
  3. runs tests
  4. commits "Release v<version>"
  5. creates tag v<version>
  6. pushes master and tag unless --no-push is passed
  7. creates a local .btcpay package unless --no-package is passed
  8. prints the Plugin Builder form values

Every Plugin Builder build starts as a pre-release. After validation, press
Release in the Plugin Builder UI to make that same build public.
