Describe the bug

The custom markdown pre-processor transformMarkdownLinks in lib/markdownUtils.ts (used by StyledMarkdown.tsx) uses a regular expression that breaks standard Markdown reference links. Specifically, it fails to parse implicit reference links (like [text][]) and completely ignores collapsed reference links ([text]).
This negatively impacts the authoring experience because contributors writing documentation have to redundantly type out their reference links (e.g., [JSON Schema][JSON Schema]) just to appease the custom parser, deviating from standard Markdown spec behavior.

Steps To Reproduce

1. Author or preview any markdown file in the website that uses StyledMarkdown.tsx.
2. Add a standard empty bracket reference link: Here is a [link][] and define it below: [link]: https://example.com
3. Add a collapsed reference link: Here is a [link] and define it below.
4. Render the page.
5. See error: The links are not converted to anchor tags; they render as raw text.

Expected Behavior

Both [link][] and [link] should be correctly parsed and converted into standard inline markdown links [link](https://example.com). The regex should fallback to matching the primary text if the secondary ID block is empty or missing.
