Put the preview notice at the top of the subsection instead of at the bottom

[gijswijs]

What is the current behavior?

The preview notice is shown at the bottom of a subsection. This makes it very easy to overlook. (e.g: https://docs.github.com/en/free-pro-team@latest/rest/reference/repos#create-a-repository-using-a-template)

What changes are you suggesting?

I suggest putting the preview notice on top of the subsection directly below the heading. This was also the behavior in the old documentation. See: https://developer.github.com/v3/repos/#create-a-repository-using-a-template

Hey @gijswijs Thank you for raising this issue! I agree that the preview note could use better visibility. We will look at this problem holistically and consider some different ideas including moving the note.

We're looking at this internally since it would be such an overarching change!
