Fix RSS Feed

[V4ldum]

The RSS feed is currently broken: it shows all pages from the website, not just blog posts, and the URL for posts is wrong.

Currently, a post's URL looks like this:

https://getflocked.dev/blog///blog/posts/talking-flock-with-viktor-lidholt/

To fix the RSS feed containing all pages, I excluded them by default and included only blog posts using the data.yaml. I also fixed the URL of the posts by removing the path from the website's URL in the RSS configuration.

Now, the URL looks like this:

https://getflocked.dev//blog/posts/talking-flock-with-viktor-lidholt/

I did not find a way to remove the double slash, but I don't think it will be an issue for most browsers. If you know how to remove it please point me in the correct direction.
