[BUG]: downloadDriverFile failing on Utils.fetchFile using microsoft-spark-3-2_2.12-2.1.0 on a 10.4 LTS (includes Apache Spark 3.2.1, Scala 2.12)

**Describe the bug**
I am trying to upgrade my spark-submit job in azure databricks to use the newest dotnet spark version. I have upgraded the version number in db-init.sh, upgraded my nuget package and updated the spark-submit params. I see there was a recent change in downloadDriverFile because the signature of fetchFile changed. I'm guessing I just missed something in the upgrade.

**To Reproduce**

Steps to reproduce the behavior:

1. Create an app that uses Microsoft.Spark v 2.1
Setup the db-init.sh to pull the 2.1 version:
`https://github.com/dotnet/spark/releases/download/v2.0.0/Microsoft.Spark.Worker.netcoreapp3.1.linux-x64-2.1.0.tar.gz`
2. Upload the artifacts to dbfs
3. Create a databricks job using spark-submit params similar to
`["--class","org.apache.spark.deploy.dotnet.DotnetRunner","dbfs:/FileStore/OO/OO-TestApp/microsoft-spark-3-2_2.12-2.1.0.jar","dbfs:/FileStore/OO/OO-TestApp/SparkTestApp.zip","SparkTestApp"]`
Use a 10.4 LTS cluster (includes Apache Spark 3.2.1, Scala 2.12)
