Update URLs for PezkuwiChain rebrand

This commit updates the repository and homepage URLs to point to the PezkuwiChain organization and website.

Changes:
- Updated `homepage` in `Cargo.toml` to `https://pezkuwichain.io`.
- Updated `repository` in `Cargo.toml` to `https://github.com/pezkuwichain/pez-solochain-template.git`.
- Updated `README.md` links to reflect the new organization (`pezkuwichain`) instead of `paritytech` or `substrate-developer-hub`.
- Updated Docker build tag in `.github/workflows/ci.yml`.
