Clarify striptags usage in code review feedback

[Copilot]

The PR reviewer (@pfefferle) referenced a striptags suggestion from a previous code review that failed to complete. The context is unclear since:

1. The automated code review encountered an error and did not produce review comments
2. This PR specifically addresses function renaming (removing "handle" prefix from event handlers)
3. The striptags reference likely pertains to __unstableStripHTML usage in src/social-web/components/fields/{excerpt,content}/index.tsx, which predates this PR

Current Implementation:

import { __unstableStripHTML as stripHTML } from '@wordpress/dom';

const getPlainTextExcerpt = ( item: FeedPost ): string => {
  const text = item.excerpt?.rendered || item.content?.rendered || '';
  return decodeEntities( stripHTML( text ) );
};

Action Taken:
Requested clarification on whether to replace __unstableStripHTML with the striptags npm package, or if the comment refers to a different aspect of the code.

No code changes made pending clarification, as the request is orthogonal to this PR's scope (function renaming).
