Improve blog section

[palasso]

Currently, the blog section contains most of the content on the website and contains the history of the project with important announcements. It deserves some ❤️

Here are some suggestions:

1. The links "View page source", "edit this page" etc. could be useful for portions of the website that are expected to be contributed by non-core devs. The blog section isn't that though as it consists of official announcements and news.
2. Either there should be classification of the blog posts in separate categories and/or tags or the categories should be hidden if all blog posts are "News".
3. The RSS icon is a nice touch. With that being said, my RSS feeder (RSS Guard) doesn't auto-detect the RSS feed.
4. The list of previous blog posts would appear better if organized better.

Looking through the docsy examples, I could find these examples with modified blog sections:

• https://agones.dev/site/blog/
• https://blog.kubeflow.org/
• https://www.selenium.dev/blog/

Such changes are not available via toggle-able settings and require modifications in the layout. It may make sense on deciding how the blog would look like in the end as it could affect how these changes would be implemented.

So perhaps we should figure out the ideal presentation and override the layouts in our tree then. Editing of blog posts seems a strange thing, i agree.
