Remove extra SEO description from blog post

Let me know if there is an issue with this or if you want to discuss?

Hi @pameeela,

field_description is used in both blog view page and RSS configuration. And the field_content doesn't have a Summary option that can replace it

Hi @pameeela, @l_vandamme (sorry for taking over)

I didn't add a MR until I check if it's okey for both of you

+ I replaced both field_description and field_content with body.
+ I also updated view blog page and RSS.

Feel free to ignore my fork if it doesn't respond well to your requirements.

Hmm, totally overlooked views. Let's pause this until we've confirmed the content model.

Updating with the current state. Still postponed on the larger content strategy discussion which should happen in Barcelona.

This is already done.
