remark-gfm@3.0.1 uses the unified v10 ecosystem but react-markdown@10
requires the unified v11 ecosystem. This caused 'this.getRole is not a
function' at runtime, blanking the KB viewer. Upgraded to remark-gfm@4
which is compatible.
Tables are a GitHub Flavored Markdown extension not supported by
react-markdown's default parser. Added remark-gfm plugin so tables,
strikethrough, and task lists render correctly in KB articles.
