Workflow yaml file created with Windows (CR) line breaks

[Krinkle]

In grunt-contrib-qunit, I tried to update grunt-contrib-internal from v4 to latest v6 and noticed that after running ./node_modules/.bin/grunt build-contrib (from a container with Node.js 10, and Debian 9) it created the .github/workflows/test.yml file as follows:

diff --git a/.github/workflows/test.yml b/.github/workflows/test.yml

And it modified CONTRIBUTING.md as well:

Weird, does it happen with the latest version?

@XhmikosR Yes, it is still enforcing Windows-style CRLF line breaks.

Does the repo you are including grunt-contrib-internal have the same .gitattributes file as this repo?

It's the only thing I can think of that might be causing the issue. Because the file is this repo do have LF since version 8.1.0, so theoretically if you use the same .gitattributes file you should be OK.
