pathling_install_spark() does not work

[johngrimes]

Running this function using version 6.4.1 of the library results in the following error:

trying URL 'https://archive.apache.org/dist/spark/spark-3.4.0/spark-3.4.0-bin-hadoop3.3.4.tgz'
Error in download.file(...) : 
  cannot open URL 'https://archive.apache.org/dist/spark/spark-3.4.0/spark-3.4.0-bin-hadoop3.3.4.tgz'
In addition: Warning message:

  The Spark version specified may not be available.
Please consider running `spark_available_versions()` to list all known available Spark versions.

This seems to be because pathling_spark_info() is reporting the incorrect Hadoop major version:

$spark_version
[1] "3.4.0"

$scala_version
[1] "2.12"

$hadoop_version
[1] "3.3.4"

$hadoop_major_version
[1] "3.3.4"

$delta_version
[1] "2.4.0"

$hadoop_major_version should be "3".
