chore(licensing): drop publishConfig.provenance for local first publish (#146)

Provenance generation requires GitHub OIDC (only works from CI). With
this set, local 'npm publish' / 'nx release publish' fails with
"Automatic provenance generation not supported for provider: null".

CI will still publish with provenance via NPM_CONFIG_PROVENANCE='true'
in .github/workflows/publish.yml — that env var enables provenance
without needing the package.json publishConfig flag.
