update blogpage to use proper shortcode and feeds

[mattstratton]

update the content/page/blogs.md page to use the new shortcode (some examples in there).

Is this what we're wanting to do for each entry?

- {{< bloglink url="https://www.ansible.com/blog" title="Ansible Blog" rss="https://www.ansible.com/blog/rss.xml" >}}

I think that's what I meant by this.

Alternate suggestion: remove this page since we don't often update the content?

[mattstratton]

Agreed. I’ll remove the page and remove it from nav. I’ll also make the url redirect to the homepage so it doesn’t 404.
