chore(git): Fix line endings in text  files (#4320)
chore(git): Fix line endings in text  files (#4320)

Although we said on #4315 to add just a comment in the CONTRIBUTING.md file. I think this solution will be better for the repository's health.

We could also apply this for `*.js` but it's up to you.

This is what I needed to run after I added this file:
```
git rm --cached -r .
git reset --hard
```

Fixes #4315
