fix: restore GitHub Packages publishing for @contentful packages

CI publish to GitHub Packages was silently failing because the project
.npmrc (with @contentful:registry=https://registry.npmjs.org) overrides
the CI-configured ~/.npmrc scope, causing lerna publish to target the
wrong registry without auth.

- Restore removal of project .npmrc during publish step (was in
  4d728ad, mistakenly removed in b8576a9)
- Remove silent error suppression on lerna publish from-git so
  publish failures are visible in CI
- Add publishConfig to all publishable packages as defense-in-depth
