[FLINK-7609][examples] WindowWordCount example doesn't print countWindow
output with default configs
## What is the purpose of the change
When running WindowWordCount example with no params (using default params),
no output is generated and thus printed, because the default 'window' and
'slide' value is too large (250 and 150).
The solution is to lower default 'window' and 'slide' values to probably 4
and 2
## Brief change log
Lower default 'window' and 'slide' values in this example to 4 and 2
## Verifying this change
This change is a trivial rework / code cleanup without any test coverage.
I tested the example with updated default values, and it now generates and
prints output.
