Investigate perf improvements using NVidia plugin

To utilise the NVidia GPU, use:

```
"runArgs": [
"--gpus",
"all"
],
```

in the devcontainer,

and then:

```
builder = (
SparkSession.builder.appName(workload_name)
.master("local[*]")
...
.config("spark.plugins", "com.nvidia.spark.SQLPlugin")
)

extra_packages = ["com.nvidia:rapids-4-spark_2.12:24.06.0"]

spark = configure_spark_with_delta_pip(builder, extra_packages=extra_packages).getOrCreate()
```

Start by locating the devcontainer configuration and the SparkSession setup used by the workload. Test the NVIDIA GPU settings and RAPIDS package configuration shown in the issue, then compare performance with and without them; done should include a documented conclusion about whether the change improves performance.
