don't use dangerouslySetinnnerHTML

[hacke2]

In the CommentsBody component, dangerouslySetInnerHTML is being used which could potentially lead to XSS vulnerabilities. The problematic code is:

<div
  dangerouslySetInnerHTML={{
    __html: toMarkdownHtml(typeof body === 'string' ? body : body.value, {
      gfm: true,
      breaks: false,
      pedantic: false,
      smartLists: true,
      smartypants: false,
      renderer,
    }),
  }}
></div>

Consider using a safer alternative for rendering markdown content, such as:

1. Using a secure markdown rendering library that handles sanitization
2. Implementing proper sanitization before rendering
3. Using React components to render the markdown structure instead of raw HTML
