feat: Add Support for Alternative Container Runtimes (Podman, containerd)

[zvictor]

Description:

Please add support for alternative container runtimes like Podman and containerd to trigger.dev. This will make the tool more flexible and accessible to a wider range of users. Some users prefer Podman for rootless execution, or use containerd in Kubernetes environments.

Problem:

Currently, trigger.dev requires Docker, which isn't ideal for everyone. Current blockers include:

• DEPLOY requires docker

Proposed Solution:

Allow users to specify their preferred container runtime. This could be done with:

• An environment variable (e.g., TRIGGER_CONTAINER_RUNTIME=podman).
• A setting in a config file.

The CLI would then use this setting instead of directly calling docker.

These are the changes I had to make to https://github.com/triggerdotdev/docker in order to work with Podman with relative success:
