Allow for wildcards or fail gracefully

[mgifford]

So I got this error:
mgifford/o-hat-scanner#13

I believe because of:
o-hat-scanner/runs/*

In the config here https://github.com/mgifford/o-hat-scanner/blob/main/.github/workflows/a11y-scan_gh.yml

Before I commented it out, I was hoping to be able to get back a wildcard of URLs:
https://mgifford.github.io/o-hat-scanner/runs/*

Instead it flagged An accessibility scan flagged the element <strong>File not found</strong>

That's a GitHub issue if it is one, not one tied to my project.

So this should fail more gracefully.

Call log:
  - navigating to "# https://mgifford.github.io/o-hat-scanner/runs/*", waiting until "load"

Apparently this isn't a good way to comment out a line here..
