[Bug]: Documentation references config.yml, by default hugo.yaml

### What happened? Using the default setup instructions puts the config for hugo into `hugo.yaml` instead of `config.yaml` ### Steps to reproduce 1. `hugo new site MyFreshWebsite --format yaml` (for version hugo v0.152.2+extended linux/amd64 BuildDate=2025-12-14T00:00:00+00:00 VendorInfo=Fedora:0.152.2-1.fc43) 2. See that there is no `config.yml` but `hugo.yaml` ### Hugo Version Hugo >= 0.146.0 (Recommended - Minimum version required for PaperMod) ### PaperMod Version commit 7d061d56d4664bd9c8241eb904994c98b928f0c8 ### What kind of devices are you seeing the problem on? _No response_ ### What browsers are you seeing the problem on? _No response_ ### Browser Version _No response_ ### Relevant log output ```shell no relevant log ``` ### Repository/Source Code link where this issue can be reproduced _No response_ ### Code of Conduct - [x] I agree to follow this project's Code of Conduct
