Add note about old website

Hi.

when I have a look at spaceapi.net, I do not see that spaceapi.io does exist. I think, the redirect could be more prominent.

We do not have access to spaceapi.net anymore, so we cannot add a note.

We could however add a note to spaceapi.io, explaining that spaceapi.net should not be used/shared anymore.

Thanks for the answer. I now use https://spaceapi.io
