Update composer-schema.json file path

Fixes #254

At the moment I am considering turning this project from a composer plugin into a stand-alone command-line tool, similar to how @icanhazstring has turned icanhazstring/composer-unused into a stand-aline command-line tool.

I believe this could solve a lot of problems, from

• Plugin doesn't work when using http proxy #80
• Fix: Use localheinz/diff instead of sebastian/diff #207
• Wrong schema file path #254

What do you think?

Same issue here:

I'm on Debian.

Closing in favor of #273.

Released with 2.0.1.

Thank you for your patience, @homersimpsons and @natanfelles - and apologies for the troubles!

@localheinz a composer plugin might be a nice idea too. In fact once globally installed one can easily go through his projects to update them. (We have discussed some other options in #254 too)
