Remove package-lock.json

[marcoroth]

The package.json states that we should be using yarn:

skills/package.json

Line 29 in d3a7f14

"npm": "please-use-yarn",

Though we still have the package-lock.json checked into the repo, which is usually an artifact generated by npm.

Bundlers like yarn also warn you about this when running yarn install:

❯ yarn install 
warning package-lock.json found. Your project contains lock files generated by tools other than Yarn. It is advised not
 to mix package managers in order to avoid resolution inconsistencies caused by unsynchronized lock files. To clear thi
s warning, remove package-lock.json.

That's why I thought I open this pull request to remove the package-lock.json since we are not using npm.

Heya @marcoroth
Thanks a lot for your PRs, I was on holidays the last two weeks so forgive my delayed response.

You are of course very correct, someone must have pushed this by accident.

I'll be looking at your other PR in the next few days. ✌️

P.S: I enjoyed your talk at RubyConf a lot and it is a big joy to see a PR of yours!
