ci: restore Ruby PATH export for fastlane step

act_runner does not carry setup-ruby's PATH changes into later steps,
so without this the step runs the toolcache default Ruby (3.3.11) and
bundler cannot find the gems installed for 3.1.7.

+## Release Workflow
+- iOS release tags use the annotated tag namespace `release/ios/vX.Y.Z`; increment from the latest existing `release/ios/v*` tag.
+- Tag message convention is `ios: X.Y.Z`, for example `git tag -a release/ios/v1.13.5 -m "ios: 1.13.5"`.
+- Push the release commit and tag together with `git push origin <branch> release/ios/vX.Y.Z`.
+- Fastlane derives the marketing version from the release tag and stamps `ios/Apps/Sybil/project.yml` during CI, so do not manually bump `MARKETING_VERSION` for normal tagged releases unless explicitly requested.
