Multiple false-positive findings in flyway-core

### Description

Scanning flyway-core with ScanCode 30.1.0 results in multiple findings of `LicenseRef-scancode-proprietary-license` which IMO are false-positives.

The matched lines are in all `package-info.java` files lines 14-17:
```
* limitations under the License.
*/
/**
* The main Flyway package and for most users, the only one they'll ever need to know about.
```

Another `LicenseRef-scancode-proprietary-license` finding which is also a false-positive finding is in `org/flywaydb/core/Flyway.java` lines 350-366:
```
throw new org.flywaydb.core.internal.license.FlywayTeamsUpgradeRequiredException("undo");

}

private CleanResult doClean(Database database, SchemaHistory schemaHistory, Schema defaultSchema, Schema[] schemas, CallbackExecutor callbackExecutor) {
