Update the pics in [demo](https://github.com/facebook/ktfmt#demo)

[atulgpt]

I tried with the latest ktlint and tried to run the sample code shown in the demo. And some of the result is updated we should update the screenshot over there

My findings are as below

Original code

Formatted code

HI, @hick209 is the current code, font, and colour theme ok or is there any particular preference for it? Is there any way we can get the access to the code used to create those examples?

@atulgpt they LGTM. If you could remove any visual artifacts such as the red symbols and red squiggly line, that would be great 😃
