Description

When starting horizon on an ubuntu container in Digital Ocean App Platform, the supervisors aren't started and no error is raised.

After investigation in Horizon code, I found that horizon run exec @php etc.

Digital Ocean Horizon uses gVisor which limit the system calls that a container is allowed to run and exec isn't part of it.

It would be great to find an alternative that doesn't get stopped by container's security measures.

Steps To Reproduce

1. Start a new App in Digital Ocean app platform.
2. Set the command of the container as "php artisan horizon"
3. After the container start, run "php artisan horizon:list" in the terminal provided by DO.
4. Expect to see :
   +-------------------+-----+-------------------------------+---------+
   | Name | PID | Supervisors | Status |
   +-------------------+-----+-------------------------------+---------+
   | 6ca0d3ec7743-bib9 | 1 | None | running |
   +-------------------+-----+-------------------------------+---------+
5. also try: php artisan horizon:supervisors, and you will see "info no supervisors running"
