[CNSL-1935] Add automated release PR workflow

Add GitHub Actions workflow that automatically creates release PRs when
pending-deploy-* branches are merged to main. The workflow updates
go.mod for major version changes, updates config.yaml with the new
version, and regenerates the OpenAPI client to automatically update all
generated files (README.md, docs/README.md,
pkg/client/configuration.go).
