Delete robots.txt

[MarcusOtter]

Changes

Removes robots.txt from the starter example. Disallow: / is not a great default value, and the file doesn't serve much purpose.
From @Princesseuh:

Hmm, I feel like the file just shouldn't be there. There's already a favicon.ico that shows how the folder work in addition of actually being useful, whereas the robots.txt effectively isn't useful to the starter

The file has also been removed from other examples (for example, minimal).

I think I’m on board with this change, unless there’s a good reason to swap it with a better default robots.txt file.

Yea, this seems like a good improvement. Thank you, @MarcusOtter!
