When throwing ConfigMissingError, keep error message succint

[AbhinavMir]

here, Solhint throws the error trace from Node itself, this is a little distracting because the error is of the format

<location of error>
<actual error>
<the entire trace>

But a better format IMO would be just showing the actual error and then presenting a potential fix.

To reproduce:

1. .solhint.json

{
  "extends": "willThrowError"
}

2. solhint <command>
