Fix documentation for setting Java I/O temp dir 

This commit fixes the documentation for configuring the Java I/O temp
dir which incorrectly suggested using the -D flag as a parameter on the
command line; these flags have been removed and should now be specified
as arguments to the JVM using either the ES_JAVA_OPTS environment
variable or using the jvm.options configuration file.

Closes #20652
