While this being okay for pixi shell-hook -s bash, this doesn't work for pixi shell-hook --json as there is no real order in a JSON object. This breaks activate-environment: true in setup-pixi.

[ruben-arts]

This is indeed how we decided to merge it right now. This does work in the tasks (env = OPENSSL_DIR="$CONDA_PREFIX") as there it is a deno task shell evaluated value. But in the activation env or scripts they are simply send to the activation handler. for shell and shell hook that is the shell itself.

It would be better if we could evaluate the values with the deno_task_shell and then export the values as is. But this would become pretty slow.
