Updated minimum Python version to 3.8 (#10)

* Removed `pytest` package from library requirements. Removed specific version requirement from the `pyyaml` package in the library requirements.

* Updated the minimum Python version to 3.8+ in the project README and pyproject.toml. Additionally, updated the project test, build, and release workflows to use Ubuntu 20.04 as the default environment as well as the Python setup action to target Python 3.8.
