docs: add impofration how to enable @debug output

This PR contains a:

• bugfix
• [x ] new feature
• code refactor
• test update
• typo fix
• metadata update

Motivation / Use-Case

1. The debug message on each line is too long because the output contains an absolute file before self message.
   Here was changed debug message formatting to: [debug:line:column] message.
2. In readme is added "How to enable @debug output", because since sass-loader 1.12.0 the output of @debug is disabled by default.

Details see in the issue.

Can you fix an error error?

This is not code error, this is Lint error:

[lint:prettier] src/utils.js
ERROR: "lint:prettier" exited with 1.
Error: Process completed with exit code 1.

It was already in master before I cloned it.

I try to find the error. I can reproduce this issue by me local with npm run lint

[alexander-akait]

Yes, can you fix it?

[webdiscus]

Yes, can you fix it?

Yes, I can.
Now are passed both the lint and the tests.
