fix: run changesets publish via package script (#556)

## Summary
- add a `release-packages` script that builds and then publishes
- update `changesets/action` to call that script instead of passing `&&`
in the `publish` input

## Why
The release workflow on `main` is currently failing inside
`changesets/action` because it tries to execute `yarn build && yarn
release` as argv, and Yarn treats `&&` as an unexpected argument.
