Linter comment workflow breaks if the repo fork is renamed

[freundTech]

Bug:

I just noticed that the make comment for staged-recipes linter workflow breaks when the head repository has been renamed.
In my case, I renamed my fork from freundTech/staged-recipes to freundTech/conda-forge-staged-recipes, but other users have also done so.
Here is an example of a failing workflow run.
The problem seems to be that the python script always assumes the head repo to be {args.head_repo_owner}/staged-recipes in line 44.
