[PATCH 3/6] doc: fix miss blank line in testpmd flow syntax doc

[Michael Baum <michaelba@nvidia.com>]

In flow syntax documentation, there is example for create pattern
template.

Before the example, miss a blank line causing it to look regular bold
text.
In addition, inside the example, it uses tab instead of spaces which
expand the indentation in one line.

This patch adds the blank line and replaces tab with spaces.
