Consider keeping the deploy preview URLs when publishing & shortening

We have a check while shortening that converts back all non profiler.firefox.com urls:
https://github.com/firefox-devtools/profiler/blob/6b0146209d963aaa1154a9777b71a9125f5b822b/src/utils/shorten-url.js#L13-L19

I think this is useful when we are working on `localhost`, but I don't think this is exactly what we need for deploy previews. When I'm working on a deploy preview, I usually want to preserve the deploy preview URL when publishing, so I can send it to other people. But this check is making it impossible. So in that case, we resort to sending the long urls which is annoying most of the time, since the url can be very long.

So to solve this issue, it would be good to add an exception for deploy preview URLs.
