Make errors thrown more descriptive

[JureSotosek]

Hey hey 👋🏼, first of all, I want to say I love graphql-code-generator, I have been using it a lot lately and it has made my life so much easier 😅I want to help improve it so here is my little contribution, hope you consider it 🤞🏼

The problem I had:
I was working on one of my projects when I decided to add the typescript-react-apollo plugin. It keept throwing an error (Plugin "typescript-react-apollo" validation failed:), which is kind of undescriptive.

After digging into the code I figured out the problem but also realized that there are details to the errors that are not being displayed. Especially in my case, it would have really helped me out.

My solution
Display the details of the errors and make it easier for the user to debug their program.

The listr-renderer.ts now includes the errors's details field, later called msg, in all of the errors that are being thrown.

Example
The problem I was having was that typescript-react-apollo requires that the extension of the generated file is .tsx. So the error I was getting before was:

The error after my fix:

Way clearer, in my opinion!

Also, here's the repo of the example from above: https://github.com/JureSotosek/graphql-codegen-errors-example

Let me know what you think 💪🏼

Thank you @JureSotosek ! I think we changed it during the last version fixes, and never changed it back.
