Remove unnecessary add-opens compiler configurations

When building, the following warning is logged for every module:
```
[INFO] --- compiler:3.11.0:compile (default-compile) @ data-locality ---
[INFO] Changes detected - recompiling the module! :source
[INFO] Compiling 4 source files with javac [debug release 17] to target/classes
[WARNING] --add-opens has no effect at compile time
```

The `add-opens` workaround is [no longer required with newer versions of Lombok](projectlombok/lombok#2681) anyway and so should instead be removed.
