[Faboslav]

Description

Hello there, i am trying to do little bit more complex action on my side, my github (matrix)context is like the following for this specific run:

2024-01-20T13:23:49.7956867Z   workflow-job-context: {
  "branch": "1.19.2",
  "mod_loader": "fabric",
  "supported_mod_loaders": [
    "fabric",
    "quilt"
  ],
  "curseforge_id": "779833",
  "modrinth_id": "ECOSu6pa"
}

If i want to use mentioned supported_mod_loaders in the loaders field as following:
${{ matrix.supported_mod_loaders }} it doesnt work with error:
Error: The template is not valid. .github/workflows/publish.yml (Line: 139, Col: 30): A sequence was not expected.
