Rat Check not Detecting Malformed Licenses

### Describe the bug

I accidentally left this typo https://github.com/apache/polaris/pull/1969 in the Spark Client build file, but rat check did not mark the license as wrong and instead said it was correctly licensed as Apache.

```
AL /Users/rspitzer/repos/polaris/plugins/spark/v3.5/spark/build.gradle.kts
```

We should determine exactly why this is happening, although it may be a bug in rat itself

Start with the RAT check for plugins/spark/v3.5/spark/build.gradle.kts and compare the malformed AL entry with the reported Apache result. Trace the relevant build configuration or RAT behavior to determine why the file is accepted; done means the cause is documented and a regression check or confirmed upstream issue is recorded.
