Fix RSS News Feed Links

[vifino]

Currently, there is basic RSS feed support enabled so a latest news feed exists:
https://fd.io/latest/news/index.xml

However, viewing an article such as "Myth-busting DPDK in 2020" presents a link to
https://fd.io/latest/news/dpdk2020/ which is.. practically useless.

The link should be the same as what the "read more" button points to.
In this case: https://nextgeninfra.io/dpdk-myth-busting-2020/
