Checks for the presence of captions or transcripts for <video> and <audio> elements.
This check looks for `<video>` or `<audio>` elements and verifies if they have associated captions or transcripts.
Users who are deaf or hard of hearing require captions to understand the audio content of a video. Audio content should have a text transcript available.
Without captions or transcripts, multimedia content is completely inaccessible to users with hearing impairments.
