Related issue

This PR references issue #1301.

What changed

• Add the ChatOps command /create-test-image.

Checklist

• I discussed the approach on the linked issue before starting (or this is a trivial fix: typo, docs, obvious one-liner)
• This PR is focused on a single change
• I ran npm run format in ui/leafwiki-ui (and in e2e if e2e tests changed)
• I updated the documentation if needed

@Hugo-Galley Thanks for the PR. I will take a look soon. Hopefully this is fine for you.

I fixed the trivy issue already in a different PR. So it looks good so far.

Hi @Hugo-Galley could you rebase?

Hi @perber,

Sorry, I’m currently on vacation and don’t have access to my PC. I won’t be able to work on this until early September.

I wanted to open the PR before leaving so it was already available for review. I’ll rebase it and address any feedback once I’m back in September.

Thanks for your patience!
