Fix dependencies problem and update tests

[esparig]

This pull request updates the project's packaging and CI workflows to improve version management, dependency handling, and release accuracy. The most important changes focus on dynamically determining the package version during release, simplifying dependency specifications, and ensuring development dependencies are installed correctly in CI.

Release workflow improvements:

• The release build workflow now dynamically extracts the package version using setuptools-scm and exposes it as an output, enabling other workflow steps to use the exact version number.
• The PyPI project URL in the deployment environment now includes the precise version number, ensuring that release links point to the correct versioned package.

Dependency management:

• Dependency version constraints in pyproject.toml have been relaxed for both core and development dependencies, removing minimum version requirements to allow for greater flexibility and compatibility.

Continuous integration enhancements:

• The test workflow now installs the package in editable mode with all development dependencies using pip install -e .[dev], ensuring that all necessary tools and libraries for testing are available in the CI environment.

Pull Request Overview

This PR addresses dependency management issues and updates CI/CD workflows to use proper project metadata and versioning. The changes modernize the build process by leveraging setuptools-scm for version management and using editable installs with optional dependencies.

• Remove version constraints from most dependencies while pinning webdavclient3 to a specific version
• Update test workflow to use editable install with dev dependencies instead of manual package installation
• Add version extraction from setuptools-scm and use it for PyPI URL generation in release workflow
