Podman guide for Linux is incorrect

[peter-777]

Describe the bug

After following the guide to enable the Podman socket and exporting the environment variables, an error occurs when starting quarkus dev.

I found that it is necessary to prepend 'unix:' when setting the environment variables.
When executing the following command, the startup proceeds without issues:
export DOCKER_HOST=$(podman info --format 'unix:{{.Host.RemoteSocket.Path}}')

Expected behavior

Testcontainers can be used with quarkus dev without any errors occurring.

Actual behavior

The following error occurs, causing the startup of quarkus dev to fail.
I have removed the PATH from the logs.
