#57: Fix imports and dependencies

Aparently we now need to stop relying on
```
            <groupId>org.glassfish</groupId>
            <artifactId>jakarta.json</artifactId>
            <version>2.0.1</version>
```
and instead use
```
            <groupId>org.eclipse.parsson</groupId>
            <artifactId>parsson</artifactId>
            <version>1.1.4</version>
```
