Remove Slicing from DiagnosticReport.categor

[Should be inherited from the base](https://simplifier.net/packages/hl7.fhir.uv.genomics-reporting/3.0.0/files/2682262/~json). e.g,
"id": "DiagnosticReport.category",
"path": "DiagnosticReport.category",
"slicing": {
"discriminator": [
{
"type": "value",
"path": "coding"
}
],
