Update install.sh

[phrxmd]

WP_BOX should be visible to launcher.sh

📝 Description

The WP_BOX environment variable is defined in box_run.sh, however launcher.sh cannot see it. It should either be exported or passed to launcher.sh directly.

In addition, because box_run.sh is a shell script, it should contain a shebang line.

📑 Context

This goes halfway towards fixing #250.
