CP Blueprint fieldtype(s) & content not being removed from published pages

[archoda]

Bug description

When you edit a blueprint and add a content field type. You can go to a page, add and publish content. It works fine. But, when you remove that field from the blueprint, then republish that corresponding page it doesn't remove the old blueprint field and data in the YAML.

How to reproduce

1. Go to Blueprints -> Pages.
2. Add a simple Text FieldType, call it 'simple' save
3. Navigate to Collections -> Pages -> [Any Page] and ADD content to the 'simple' field and publish
4. Find the file 'content/collections/pages[pagename].md' to ensure it added and published the content
5. Navigate to Collections -> Pages -> [Any Page] and REMOVE content to the 'simple' field and re-publish
6. Find the file 'content/collections/pages[pagename].md' and see it keeps the 'simple' field and content

You're allowed to have any arbitrary data in your entries. They don't all have to be part of the blueprint. We don't remove any content.
