Update 'How Gatsby works doc': CNAME file should be copied in public folder

[angelogulina]

Though the build process is working perfectly, it seems to me that, as suggested, theCNAME should be in the public folder in order to get into the right place for GitHub to recognize.

(I'm really new to this project so if I'm wrong, I would be glad to receive feedback if this PR is wrong 🙏)

Hi!
The issue you linked already has the right answer: Put it into the static folder as it gets copied over. Normally you don't have access to the public folder in a CI as Netlify anyway and therefore can't copy it over manually.
The docs also describe that:
https://www.gatsbyjs.org/docs/adding-images-fonts-files/#using-the-static-folder

Thanks for the PR though (I'll close this one)

@LekoArts thanks for you reply.
I'm just curious: has anybody tried or experienced that anyway?
I'm hosting my website on gh pages since today and if I don't put the CNAME in public, it gets to static and github doesn't seem to find it.

You need to put it into the static folder (same directory as your src folder) as described in the doc. I'm not talking about the static folder of the „gatsby build“!
