start-local-podman: Fix loading .env in success()

[agunnerson-elastic]

create_installation_folder() will cd to the data directory for the duration of the script, so .env is actually in the cwd.

---

This fixes:

❯ curl -fsSL https://elastic.co/start-local-podman | ES_LOCAL_DIR=data-9.3.2 ES_LOCAL_PASSWORD="changeme" sh -s -- -v 9.3.2
