doxygen html cannot be opened from CI artifacts
@adam-mercer @karl-wette @duncanmmacleod : When going to the "doxygen" step of a pipeline, then click on "browse" under "artifacts" in the sidebar, I think I used to be able to see the html directly without downloading. Now it still displays the directory hierarchy to click through, e.g. https://git.ligo.org/karl-wette/lalsuite/-/jobs/1142589/artifacts/browse/opt/lalsuite/share/doc/ but when opening any file, it becomes 404: https://karl-wette.docs.ligo.org/-/lalsuite/-/jobs/1142589/artifacts/opt/lalsuite/share/doc/index.html
It doesn't seem to be a simple permission issue either, since I get the same for CIs run on my own fork (e.g. here).
