Add parelized tests

[erseco]

This pull request introduces improvements to the testing workflow and development environment setup. The main changes are the addition of parallel test execution for local and staging environments, and the introduction of a dedicated set of optional development dependencies in pyproject.toml for easier setup. The help output in the Makefile is also updated to reflect these changes.

Testing workflow improvements:

• Enabled parallel execution of tests for both local and staging environments by adding the -n auto flag to the pytest commands in the Makefile.
• Updated the help section in the Makefile to indicate that tests are now run in parallel.

Development environment setup:

• Added a [project.optional-dependencies] section named dev in pyproject.toml, listing common development tools such as pytest, flake8, black, mypy, and documentation generators for easier developer onboarding and environment consistency.
• Removed the strict version pinning for rich in pyproject.toml to allow for greater flexibility in dependency management.
