scroll-to-text-fragment

[pprados]

The [scroll-to-text-fragment](https://github.com/WICG/scroll-to-text-fragment) specification allows adding a URL fragment that highlights specific text on a page. This is particularly useful for referencing a part of a webpage from a search engine or for generative AI projects such as RAG (Retrieval-Augmented Generation). However, this functionality is only available for HTML pages.

PDFViewer complies with RFC 3778, which allows specifying a page to display.

I believe it would be highly beneficial for all RAG projects working with PDF documents to extend PDFViewer to support the [scroll-to-text-fragment](https://github.com/WICG/scroll-to-text-fragment) specifications.

While there are some implementations using frameworks like React or others, they do not offer the pure JavaScript approach provided by pdf.js.

Do you think this feature could be implemented?
