I'm hoping that this will resolve the error in #2018, which fails with:
ReferenceError: ReadableStream is not defined and

npm WARN EBADENGINE Unsupported engine {
npm WARN EBADENGINE   package: 'whatwg-mimetype@4.0.0',
npm WARN EBADENGINE   required: { node: '>=18' },
npm WARN EBADENGINE   current: { node: 'v16.20.2', npm: '8.19.4' }
npm WARN EBADENGINE }

Will test in the pipeline

The pipeline failed, so before we can see if the unsupported engine issue above is resolved, the new pipeline error needs to be fixed.
After investigating a little further, it seems like there might be an issue when checking multiple files for broken links at once, so the 2nd commit checks 1 file at a time as a workaround.
