Thanks @ianmkenney. Could you please add a line commenting what this does in the file?

If you've tested this locally by making a cookie and creating docs, would you mind uploading that to this PR as well? It's not somehting we look for in the CI (although perhaps it should be).

@lilyminium I ran into it when making the mdaencore docs. I couldn't find any other way to ignore a module in the autosummary directive.

I tested this by running the cookiecutter, and it removed tests for me -- thanks @ianmkenney! However, we should use the variable for the package name instead of the project.

Thanks for merging, @ianmkenney! Just for next time, a "Request changes" review is conventionally blocking and requires resolution and re-review before merging -- my fault for not setting up the ruleset on this repo before this PR, but just explaining why I've done so now.
