publish docker image to docker hub automatically when a release is done

[AlessandroMinoccheri]

I am using the same strategy in this repo:
https://github.com/phparkitect/arkitect/blob/main/.github/workflows/build.yml

So when a new release is created, GitHub Actions automatically push the docker image with a tag into the docker hub.
It's important to add in the repository two secrets: DOCKERHUB_USERNAME, DOCKERHUB_TOKEN

v3 ?

I haven't already tried v3

Should work without issues, but lets keep it for now

Done ✅

I will create a release

[OskarStark]

Hmm, do we need to change something here?

on:
    workflow_dispatch:
    schedule:
        - cron: '30 */4 * * *'

This is for the auto-commit I think.
So if a commit is done, the docker image should not be pushed because the trigger is a new release. Right?

Ok I triggered it manually for now, but an error occurred:

That image not exists I think, I changed our docker too, see this commit @OskarStark

Hi @AlessandroMinoccheri, thanks again for this PR; I try to adapt it for the other repo in:
OskarStark/php-cs-fixer-ga#102

Unfortunately, I think because PHP-CS-Fixer uses v1.1.1 instead of 1.1.1 it cannot extract the version and the Workflow is failing:
https://github.com/OskarStark/php-cs-fixer-ga/actions/runs/6046366956

Maybe you can have a look and propose a PR? That would help me a lot, thank you!

BTW, I invited you as a collaborator, so that you can trigger the workflow manually!

Thanks in advance! ❤️
