ci: re-enable pezsc-basic-authorship doc tests and pezsnowbridge-runtime-common bench checks

- Remove pezsc-basic-authorship from doc test exclusions (exclusion was
  copy-pasted from zombienet-sdk-tests, no actual doc issue exists)
- Remove pezsnowbridge-runtime-common from bench check exclusions
  (try_successful_origin is properly implemented for both ForeignAssetOwner
  and LocalAssetOwner with runtime-benchmarks feature gate)
