chore: Enable npm package provenance for all published packages
This commit adds `provenance: true` to the `publishConfig` section of all main publishable packages:
- @swc/core
- @swc/helpers
- @swc/html
- @swc/minifier
- @swc/react-compiler
- @swc/types
Package provenance provides transparency about how and where packages are built and published, enhancing supply chain security by allowing users to verify the authenticity and origin of published packages.
