Fix bookshop native images tests in outbound test pipeline (#683)

Currently, outbound tests for bookshop native images are failing with
error
```
 The configured GraalVM reachability metadata repository at /home/jenkins/agent/workspace/ices-outbound-tests_nightly_main/bookshop-native-image/srv/target/graalvm-reachability-metadata/7de5023997d2db6ebc9d2d50543cec2be999dfb7 does not contain a 'schemas' directory. Requires GraalVM Reachability Metadata 0.3.33 or newer which packages the required schemas
```

This PR is updating the reachability metadata.
