feat(button): update config

[finger563]

Description

• Allow button task stack size to be configured
• Rebuild docs

Motivation and Context

Right now the Button task had a fixed stack size of 4KB, which works for simple examples, but if the user starts doing a lot of processing / utilizing a lot of stack within the callback function provided then the task can run out of stack space. This update allows the user to customize the amount of stack space allocated to the button task.

How has this been tested?

Building the button example.
