Lombok causes com.google.errorprone.SourcePositionException in UnusedVariable

Compilation fails when lombok annotation `@Slf4j` is placed on a class, but the logger is not used, causing build to fail.

Example:
```
@Slf4j
class A {

public void doSomething() {
// logic without using log generated by @Slf4j
}
}
```

Stacktrace:

```

Start by reproducing the @Slf4j example with Error Prone 2.50.0, then read UnusedVariable.buildUnusedVarFixes and SuggestedFixes.replaceIncludingComments from the stack trace. Look for existing UnusedVariable tests and add a regression case for the generated unused logger; done means compilation no longer throws SourcePositionException.
