How This PR Solves The Issue

• bump to v2

Manual Testing Instructions

• setup ddev in codespaces, check test project

Beware: setup_test_project.sh currently fails with

2023-07-02 09:41:48.611Z: + ddev delete -Oy tmp
2023-07-02 09:41:49.204Z: Failed to get project(s): could not find requested project 'tmp', you may need to use "ddev start" to add it to the project catalog
2023-07-02 09:41:49.297Z: postCreateCommand failed with exit code 1. Skipping any further user-provided commands.

I did full rebuilds, it failed on docker-in-docker v1 as well as v2.

Thanks, looks good!

You can fix the mentioned issue in the script by changing line 10 to ddev delete -Oy tmp >/dev/null || true.

We'll do a new package build for this.

This seems fine. We can push this to new package even before pulling it if we want to, makes it easy to test on Codespaces that way.

@mandrasch I hope you'll take a look and see how this is working for you. All the various related PRs should be pulled, and new package has been created.
