Remove eval() call from the bundle

[duailibe]

The TOML parser has a eval("require('util')").inspect in the code, which makes Prettier fail when loading in some environments. We'll replace it for require("util").inspect in the bundle.

Fixes #6053

Should we add this to the CHANGELOG? If so, can you help me how to phrase it?

Something like this, maybe?

Prettier now works when run inside the Atom editor again. Atom has a security feature where code containing eval is not allowed to be run. One of Prettier's dependencies uses eval to prevent bundlers from including debug code. We've now made sure that this eval does not end up in the code we ship to npm, making Prettier play nice with Atom again.
