Support `push --all-tags` to push all tags

[anitakrueger]

Description

The push command despite making the tag optional, does not push all tagged local images like docker push does (https://docs.docker.com/reference/cli/docker/image/push/#all-tags). I see this is documented in the command reference, but is there a reason?

In addition, we need to push tags and the image needs an soci index. At the moment, I have to run 2 nerdctl push commands and the second one will overwrite the firsts soci index.

Steps to reproduce the issue

1. run nerdctl tag twice and then push without a tag

nerdctl tag ${{ steps.login-ecr-pull.outputs.registry }}/${{ inputs.pull_repo }}:${{ inputs.image_tag }} ${{ steps.login-ecr-push.outputs.registry }}/${{ inputs.push_repo }}:${{ inputs.image_tag }}
nerdctl tag ${{ steps.login-ecr-pull.outputs.registry }}/${{ inputs.pull_repo }}:${{ inputs.image_tag }} ${{ steps.login-ecr-push.outputs.registry }}/${{ inputs.push_repo }}:latest
nerdctl push --soci-min-layer-size ${{ inputs.soci-min-layer-size }} --snapshotter soci ${{ steps.login-ecr-push.outputs.registry }}/${{ inputs.push_repo }}

2. Only the latest tag will show up in the registry.

Describe the results you received and expected

Only the latest tag is pushed, the other tag is not.

Hi! Me (@yashkukrecha), @ShivanshNikhra, and @aravsrid are a group of three students working on open-source issues for our virtualization course. We’re interested in taking on this issue and coordinating the work among ourselves to submit a single PR.

We estimate we can complete it within the next month. Would it be okay if we proceed with this issue? If you prefer assignments, we’re happy to be assigned as well. Thanks!

Hi @AkihiroSuda, can you review the PR I submitted for this issue whenever possible? Thanks!
