Situation

The currently used markdown-link-check@3.13.7 has two shortcomings that are apparent in this repo:

• It logs an HTTP 403 Forbidden error checking https://www.npmjs.com/
• It reports success although there were link errors

Change

• Update to markdown-link-check@3.14.1
• Add markdownLinkConfig.json to ignore checking any links in the domain https://www.npmjs.com (see https://github.com/orgs/community/discussions/174098 for background information)

Verification

npm ci
npm run check:markdown-links

Confirm no bad links reported

cat > missing.md <<EOT
[bad link](https://github.com/cypress-io/github-action/missing.md)
EOT
npm run check:markdown-links
echo "exit status should be non-zero for failure: " $?
rm missing.md

Check that a non-zero exit status is reported when a deliberate link error is checked.
