Review Comment:
Replaced it with `GcFinalization.awaitFullGc` in rebased commit,
[a0204a3](https://github.com/apache/iceberg/pull/5862/commits/a0204a38955188c70e2dcc7f9b3ff2a7e74fc949).
I understand `iceberg-bundled-guava` relocate guava namespace from
`com.google.common` to `org.apache.iceberg.relocated.com.google.common`. I
don't know if and how to treat `guava-testlib` the same way.
