Research direction
Investigate the Bootlint source code (likely bootlint.js) to find how Bootstrap versions are detected from CDN URLs. Look for patterns matching Bootstrap CDN links (e.g., stackpath.bootstrapcdn.com) and ensure that v4 URLs are included. Check the referenced comment in issue #18495 for specific details. Test with a JSFiddle that uses Bootstrap v4 CDN to confirm the detection failure.
