GitHub Codespaces provides a cloud-based development environment which you can use instead of creating and maintaining a local development environment. There is a free tier that should be sufficient for casual CircuitPython development.

GitHub user @bablokb has set up and plans to maintain GitHub Codespaces "devcontainers" for the different CIrcuitPython port builds. For more information, see Using Github Codespaces for CircuitPython Development in the Adafruit Playground. Thank you, @bablokb!
