Disable indexing by default for newly installed applications

It would be better to disable indexing by default for any newly installed applications

I guess the placeholder text is not ideal for that textarea but the default is to allow the app iteself to respond to the robots request. The docs state this more clearer https://docs.cloudron.io/apps/#robotstxt

"By default, Cloudron does not setup a robots.txt for apps. When unset, the app is free to provide it's own robots.txt."

So the default basically is not to allow all but to let the app handle it.
