What would you like help with?

I think I found a bug

How are you running Renovate?

Mend Renovate hosted app on github.com

If you're self-hosting Renovate, tell us which platform (GitHub, GitLab, etc) and which version of Renovate.

No response

Please tell us more about your question or problem

The Helmfile manager has supported multidoc YAMLs for a while (#8682), but it fails to update the corresponding lockfile if a dependency is updated (see logs). Please use the parseYaml instead of the parseSingleYaml function in the artifacts.ts.
