Introduction of the Kconfig definition file in "Development/Writing your First Application" is incorrect

[Xiaokang Yang]

The title of the incorrect content is "First Application Tutorial (Hello Sky)".

In the Minimal Application section, Step 4. The original content is:
Create and open a new Kconfig definition file named Kconfig and define your symbol for naming (see Kconfig naming convention). Copy in the text below:

P
"
n
-
p

The code is the last letter of each line. The correct code should be:

menuconfig EXAMPLE_PX4_SIMPLE_APP
    bool "PX4_SIMPLE_APP"
    default n
    ---help---
        Enable support for px4_simple_app
