fix: only read package.json for frameworks being published

- Modified renameTok8sWeb to conditionally read package.json files
- Modified revertNames to conditionally read package.json files
- Fixes ENOENT error when publishing single framework

This allows the publish script to work when only one framework
is built (e.g., FRAMEWORK=angular), without requiring both
dist folders to exist.
