Switch to pnpm

Yarn v1 is unmaintained, deprecated and full of bugs. styled-components main repo uses pnpm. So there we go!

Note: There's an alternative PR, #204, that just upgrades Yarn to the latest version.

Note: Clean migration from yarn.lock lockfile was not possible and it had to be recreated. Therefore, this PR comes with minor dependency differences. As a result, minor formatting changes were also introduced to make lint pass.
