Subject: [PATCH] [SPARK-15781][DOCUMENTATION] remove deprecated environment
variable doc
## What changes were proposed in this pull request?
Like `SPARK_JAVA_OPTS` and `SPARK_CLASSPATH`, we will remove the document for `SPARK_WORKER_INSTANCES` to discourage user not to use them. If they are actually used, SparkConf will show a warning message as before.
## How was this patch tested?
Manually tested.
Author: bomeng <bmeng@us.ibm.com>
Closes #13533 from bomeng/SPARK-15781.
