Add OrbStack to PATH in non-interactive shell

[dqbd]

When trying to connect to a remote OrbStack instance using Docker Context feature, the following error occurs.

# Using host=ssh://[host]:/Users/[username]/.orbstack/run/docker.sock

zsh:1: command not found: docker

This is due to initialisation script not being run when running a non-interactive shell. This can be remedied by adding the following line in ~/.zshenv

# Same as in .zprofile
source "$HOME/.orbstack/shell/init.zsh" 2>/dev/null || :
