Update editor to rdfa-backwards-compatibility build

[elpoelma]

Overview

This PR updates the editor to the rdfa-backwards-compatible build (lblod/ember-rdfa-editor#1155)
This build includes some API changes:

• rdfaAttrSpec is now a function
• usage of the ...WithConfig configurable nodespecs

This PR also includes some changes to the citation plugin to support the rdfaAware system.

connected issues and PRs:

lblod/ember-rdfa-editor#1155

How to test/reproduce

• pnpm start
• Visit the different dummy pages, all node-specs should be in rdfaAware mode and the rdfa-features should work as expected

Challenges/uncertainties

It does not seem very useful to also convert all the nodespecs provided by this package to be backwards compatible.

Checks PR readiness

• UI: works on smaller screen sizes
• UI: feedback for any loading/error states
• Check if dummy app is correctly updated
• Check cancel/go-back flows
• changelog
• npm lint
• no new deprecations

When trying to insert anything from the sidebar (in the index route), I get an error:

Uncaught TypeError: can't access property "indexOf", tagName is undefined

Interesting, will check if I can reproduce that.

Does it occur with a specific action?

It happens in the insertStructure command when trying to use any of the article structures in the insert menu in the sidebar. Actually, it's perhaps just insert article but once it has happened once it happens with anything from then on.

That specific issue should be fixed now, it was an issue in the toDOM function of the besluit_article_header nodespec.
I did notice that the current implementation of a decision article is far from usable, so we should probably fix it before releasing the plugins/going to embeddable.
