[MINOR] [DOC] Correct code snippet results in quick start documentation
## What changes were proposed in this pull request?
As README.md file is updated over time. Some code snippet outputs are not
correct based on new README.md file. For example:
```
scala> textFile.count()
res0: Long = 126
```
should be
```
scala> textFile.count()
res0: Long = 99
```
This pr is to correct these outputs so that new spark learners have a
correct reference.
Also, fixed a samll bug, inside current documentation, the outputs of
linesWithSpark.count() without and with cache are different (one is 15 and the
other is 19)
```
scala> val linesWithSpark = textFile.filter(line => line.contains("Spark"))
linesWithSpark: org.apache.spark.rdd.RDD[String] = MapPartitionsRDD[2] at
filter at <console>:27
scala> textFile.filter(line => line.contains("Spark")).count() // How many
lines contain "Spark"?
res3: Long = 15
...
scala> linesWithSpark.cache()
res7: linesWithSpark.type = MapPartitionsRDD[2] at filter at <console>:27
scala> linesWithSpark.count()
res8: Long = 19
```
## How was this patch tested?
