Describe the bug
Hello, it's me again with an issue similar to #126 😄.
With a config such as baseURL: http://example.com/foo/ links for affected services are broken because they again begin with /.

I've narrowed it down to a change introduced in Hugo v0.101.0 (gohugoio/hugo@a5a4422) that now treats all URLs beginning with a / as relative to the root, not to the baseURL.

Reproduction steps
Steps to reproduce the behavior:

1. cd exampleSite && hugo serve --baseUrl=http://localhost/cstate/ --theme=cstate --themesDir=../.. --verbose
2. Open http://localhost:1313/cstate/ in browser
3. Notice broken links up top for affected services (Gateway, Website, API...) both on the main page and from the little tags on individual issues.

I still have the GitLab mirror for the dev branch, currently built with Hugo v0.104.3, up at https://kurisuchan.gitlab.io/cstate/ that shows the same behavior

Context
cstate: master (8af8ff5)
hugo: v0.105.0

Additional information
Replacing /affected/... with affected/... seems to do the trick. I have a branch with those changes at zeeZ@0727f66 and could create a PR if wanted, just need a new dev branch. I've tried the change with some older versions down to v0.80.0 and nothing seems to break.
