Flatten stacks with parent in non-terminating-image checks

[thepetk]

Description of Changes

The PR fixes the issue that the check_non_terminating script faces for stacks that include a parent. An example is #401 where the changes introduced are failing.

The list of updates:

• We add a build step to the workflow.
• The build step refers to a small golang bin file which utilizes the library to parse, flatten and update the devfile.
• The necessary updates were added in the bash script to check if a parent is included in a devfile and if so to run the bin and flatten it.

Tests Performed

Explain what tests you personally ran to ensure the changes are functioning as expected.

How To Test

• Update a stack to point to a parent.
• Run minikube or create a cluster
• From project root build the binary:

go build -C tests/check_non_terminating

• Update the STACKS variable inside the tests/check_non_terminating to include only the stack you have temporarily update.
• Finally again from project root, run locally the tests/check_non_terminating.sh script.

Notes To Reviewer

I've tried to mimic the updates introduced by the PR for ollama and ran the workflow here: https://github.com/thepetk/registry/actions/runs/13076640505/job/36490341149

Couple comments/questions!

[Jdubrick]

I'm not familiar with the -C flag and I can't find much on it, what does it do?

[thepetk]

I wanted to avoid changing dirs with cd so I used the flag -C to change it on build -> here

[Jdubrick]

Suggested change

	NON_TERMINATING_MODULE_BIN="$(pwd)/tests/check_non_terminating/./check_non_terminating"
	NON_TERMINATING_MODULE_BIN="$(pwd)/tests/check_non_terminating/check_non_terminating"

Do we need the . there?

[Jdubrick]

Also if the second check_non_terminating is the binary name maybe we rename it for clarity? So it isn't doubled up in the path

[thepetk]

I made it a bit more dynamic and gave it the name flatten-parent as default (also for the workflow).
