chore: update doc links from gregberge/xstyled to styled-components/xstyled

Sweeps the root README, CONTRIBUTING, website README, and three package READMEs to point at the current repo and `main` branch. CODE_OF_CONDUCT's `hey@gregberge.com` reporting contact is intentionally left as-is: it's a personal email, not a generic redirect. Defunct david-dm and CircleCI badges are also left for a separate dead-service cleanup.

 xstyled is a small project, it is widely used but has not a lot of contributors. We're still working out the kinks to make contributing to this project as easy and transparent as possible, but we're not quite there yet. Hopefully this document makes the process for contributing clear and answers some questions that you may have.
