Use a HTTP URL for the App Store link

Markdown doesn't seem to play well with the schema macappstore://

Thank you! could you rebase so the commit only are changing the url?

[frosas]

Sorry @codler because probably I'm understanding it wrong but isn't the branch already up to date?

[frosas]

Hope you like it now :)

BTW, I'm seeing both Vim and GitHub's editor add a newline by default. I think it's the recommended behavior.

[codler]

yep, thank you!
