fix: packages compatibity issues found for Python < 3.12

[petruki]

This pull request introduces several improvements and maintenance updates across the codebase and CI configuration. The most notable changes are the addition of a compatibility module for the Self type, enhancements to dependency management for Python versions, improvements to workflow flexibility, and minor bug fixes.

Python compatibility and dependency management:

• Added a new module switcher_client/lib/compat.py to provide a version-agnostic import for the Self type, ensuring compatibility across Python versions.
• Updated pyproject.toml and Pipfile to conditionally include typing-extensions for Python ≤ 3.12, and adjusted dev dependencies for better environment setup. [1] [2]
• Updated imports in switcher_client/switcher_data.py to use Self from the new compatibility module.

CI/CD workflow improvements:

• Upgraded the SonarCloud GitHub Action to v7.1.0 in both master.yml and sonar.yml for improved scanning capabilities. [1] [2]
• Added a skip-lint input to the staging.yml workflow, allowing developers to optionally skip linting during CI runs. [1] [2]
• Removed the linting step from the master.yml workflow for streamlined testing.

Test coverage and code quality configuration:

• Updated .coveragerc and sonar-project.properties to exclude the new compatibility module from coverage and SonarCloud analysis. [1] [2]

Bug fixes and documentation:

• Fixed string formatting in error messages in switcher_client/errors/__init__.py for correct output.
• Removed the Snyk badge from README.md for a cleaner project overview.
