Pa11y and possible other dependency issues

[shumatepf]

The GitHub Action task for running pa11y is consistently failing. When upgrading pa11y to 3.0.1, the action passes but the tests still fail. I noticed this when the action triggered from dependabot bumping the pa11y version succeeded. Below is the task output for pa11y from that action:

Run npm run pa11y-ci:sitemap

> federalist-uswds-jekyll@1.3.0 pa11y-ci:sitemap /home/runner/work/uswds-site-sample/uswds-site-sample
> pa11y-ci --sitemap http://localhost:4000/sitemap.xml --sitemap-exclude "/*.pdf"  --sitemap-exclude "/admin"

Running Pa11y on 11 URLs:
 > http://localhost:4000/collections/ - Failed to run
 > http://localhost:4000/document-with-sidenav/ - Failed to run
 > http://localhost:4000/document/ - Failed to run
 > http://localhost:4000/201[9](https://github.com/shumatepf/uswds-site-sample/actions/runs/3735389750/jobs/6352134807#step:8:10)/01/[13](https://github.com/shumatepf/uswds-site-sample/actions/runs/3735389750/jobs/6352134807#step:8:14)/an-extra/ - Failed to run

This can be reproduced on any copy of the pages-uswds-jekyll template, including the one linked from the above action.

@shumatepf we've only tested the pa11y action up to version 2.4.0 and because it's pinned I think new sites should succeed on their initial builds unless the dependency is upgraded. If you're able to get 3.0.1 working, would you mind contributing back here?

@drewbo The action ran initially when creating a clone of the template failed with the same issue.

pa11y/pa11y-ci#198 actually addresses this issue, it seems to be a bug with Ubuntu-22.04.

The action runs successfully with Ubuntu-20.04.

Ah, apologies I only checked the latest builds. Good research and we can downgrade the prescribed runner in the template until this is resolved. Thanks!
