Aileen Nowak 7d388cb9e1 🐛 Fixed internal links converting to absolute URLs (#9143)
closes #9136

Changed the functionality in `make-absolute-urls.js` util to not convert the URL when starting which an `#`, as it indicates and internal link.
The util is used inside of the `{{amp_content}}` helper and to render the RSS feed. I tested the changes with the most popular RSS reader 'Feedly' and it seems like these internal links get converted to absolute URL inside of Feedly automatically.
