[Error] --additional-flags "--platform=linux/arm64" being ignored.

[overflowz]

Describe the bug
Hi, when creating an image and trying to add --additional-flags parameter, looks like it is getting ignored if I pass --platform=linux/arm64

To Reproduce
use podman as a container driver and run: distrobox create --image docker.io/arm64v8/debian --name debian --additional-flags "--platform=linux/arm64"

Expected behavior
should pull arm64 version of debian. instead, it shows this log:

Image docker.io/arm64v8/debian:latest not found.
Do you want to pull the image now? [Y/n]: Y
Trying to pull docker.io/arm64v8/debian:latest...
Error: choosing an image from manifest list docker://arm64v8/debian:latest: no image found in image index for architecture "amd64", variant "", OS "linux"

with dry-run (just posting not sure, can this extra space cause any issues too?):

--ulimit host
--userns keep-id
 --platform=linux/arm64
--entrypoint /usr/bin/entrypoint
docker.io/arm64v8/debian:latest

Desktop (please complete the following information):

• Are you using podman, docker or lilipod?: podman
• Which version or podman, docker or lilipod?: 5.3.1
• Which version of distrobox?: 1.8.0
• Which host distribution?: CachyOS
• How did you install distrobox?: pacman (CachyOS extra mirror)

Additional context
Without passing the --platform=linux/arm64, podman (docker too?) can't locate the arm version of the image.

Thank you!

Ran into a similar issue but using the --arch command line flag for podman. Simply working around it by manually executing the dry-run print allowed me to pull the image and enter it with distrobox afterwards.
