ci: trigger zombienet tests automatically

Description

#9877

[pepoviola]

Thanks @DenzelPenzel , looks good but I think this pr contains also the changes in the logs (not merged yet). And we need to make the call to the workflow in the build_images.
Thx!

All GitHub workflows were cancelled due to failure one of the required jobs.
Failed workflow url: https://github.com/paritytech/polkadot-sdk/actions/runs/18351612704
Failed job name: test-linux-stable

Looks good, thanks!!

It looks that there is a deadlock that prevents zombienet tests from starting: https://github.com/paritytech/polkadot-sdk/actions/runs/18356902291

Canceling since a deadlock was detected for concurrency group: 'Build and push images-9960' between a top level workflow and 'trigger-zombienet-cumulus'

hmm, thanks @alvicsam. I will check this erros.

[pepoviola]

@alvicsam concurrency issue is now fixed, but all the test are show in the build workflow which is not good for discovery.
Maybe we can add only one workflow that make the wait logic and trigger the rest of the workflows, so that way I think we will be covered in terms of api request. wdyt?

[alvicsam]

I don't see the problem of discoverability. All zombienet jobs are in the same list of jobs in the github UI but the name is slightly different. We can change the workflow name if you want. I would prefer not adding a wait workflow because it is error-prone and consumes API requests and we can easily avoid both issues with on: workflow_call.

off-topic: there is one job that often exceeds timeout

[pepoviola]

Yes, that test is disabled as part of this pr https://github.com/paritytech/polkadot-sdk/pull/9957/files#r2416989294.
Oks, let me think a better name but for now we can merge as is.

Thx!
