Update the project's development workflow to use Hatch

[dcruzf]

This pull request updates the project's development workflow to use Hatch as the primary environment and dependency manager, both in documentation and CI/CD pipelines. It also improves the contributing documentation for clarity and consistency. The most important changes are:

CI/CD Pipeline Updates:

• Replaced the use of uv and uvx with Hatch commands in all GitHub Actions workflows (ci.yml, publish.yml, and publish-dev.yml). This includes switching installation steps to use pypa/hatch@install and updating test, build, and publish commands to use hatch directly. [1] [2] [3]

Documentation Improvements:

• Significantly revised docs/contributing.md to clarify the development setup, emphasizing Hatch for environment management and tooling. Expanded instructions on installing dependencies, running checks, and managing environments, and improved explanations for contributing, running tests, serving/building docs, and submitting issues or PRs. [1] [2]

Project Configuration:

• Removed the [dependency-groups] section for development dependencies from pyproject.toml, reflecting the shift to managing dev dependencies via Hatch environments.
