Python autopatching does not work when Devbox is installed via Flake

[Lagoja]

What happened?

As of Devbox 0.13.6, we attempt to add Devbox to the Nix store so we can use it in the patch flake when auto-patching Python. When using Devbox installed from the Flake, the patching fails with the following error:

❯ devbox add python@3.11
Info: Adding package "python@3.11" to devbox.json
✓ Computed the Devbox environment.

Error: There was an error installing nix packages
source: nix: command error: nix --extra-experimental-features ca-derivations --option experimental-features 'nix-command flakes fetch-closure' print-dev-env --json path:/Users/johnlago/src/cling-notebook/.devbox/gen/flake: unable to download 'https://api.github.com/repos/jetify-com/devbox/commits/0.13.6-0bc66cb': HTTP error 422: exit code 1

Error: There was an internal error. Run with DEVBOX_DEBUG=1 for a detailed error message, and consider reporting it at https://github.com/jetify-com/devbox/issues
(devbox)

Simplest fix is to change the version string in the Flake to match our standard installer, though we'll probably need a different approach for non-release builds?

Steps to reproduce

1. Install devbox with nix profile install github:jetify-com/devbox/latest
2. Create a new Devbox project
3. Add Python with devbox add python
