copy explaining how to check for .gov site

[jpyuda]

Short copy explaining to users how to determine whether or not a site has a .gov URL.

Depending on where things land with usability testing, we may need to tailor this to a user's browser context (different instructions for desktop vs. mobile, for example). But for now let's start with something generic.

@kategarklavs please update this with your progress and move to "review" if appropriate

Copying the draft copy here:

The .gov means it’s official.

Official federal government sites always use a .gov domain. Before sharing sensitive information online, make sure you’re on a .gov site.
