Broken Links QA Parent

## User Story

In order to ensure our site remains up to date, datagovteam runs a weekly broken links report in several repos.

As an optional O&M task, create subtasks or attach PRs to this Parent issue that address any cleanup of these broken links, or ignoring of false positives.

The Broken Links reports live in an issue in each repo where the report runs:

| Site | Issue |
| - | - |
| resources.data.gov | https://github.com/GSA/resources.data.gov/issues/811 |
| strategy.data.gov | https://github.com/GSA/data-strategy/issues/338 |
| data.gov 11ty | https://github.com/GSA/datagov-11ty/issues/423 |
| sdg.data.gov | https://github.com/GSA/sdg-indicators-usa/issues/1140 |
