Feature/ember upgrade attempt to v5.0.0

[ValenberghsSven]

This is a combination of all PR's currently open that are needed to even consider ember upgrade.
Going to check if I can update ember to v5.0 with this.
Noted the steps I am taking and any errors I get (if any)

merged in the PR (conflicts resolved so everyone gets what they needed):

• ember acm-idm upgrade #2073 !! requires remove dispatcher line and change deprecated env property names app-kaleidos#500 !!)
• KAS-4678: Update van rdfa-editor package naar meest recente versie #2141 !! requires KAS-4678: Adjust hierarchical list type styling & sanitization and add list-marker fixes decision-report-generation-service#22 and KAS-4678: Adjust hierarchical list type styling & sanitization and add list-marker fixes minutes-report-generation-service#16
• KAS-4908 upgraded mock-login package to most recent #2252
• KAS-4911 upgrade easier dependencies #2253

What did I do after merging:

npm uninstall -g ember-cli    
npm install -g [email protected]
ember-cli-update --run-codemods --config config/anglebrackets-codemod-config.json
ember-cli-update upgrade --to 5.0.0

• added the config for codemods since it tries to change all anglebrackets (like helpers) to components. It shouldn't.
• bumped ember-power-select to next major to fix issue
• fixed adapters using relationship.meta.key to relation.key. It seems the meta is no longer a thing 🤷‍♂️
• removed import EmberError from '@ember/error'; from modelWithModifier, no longer worked. Error still gets thrown all the same (more concurrency testing will be wise)
• fix polymorphism of document-type (has base model concept) to properly and explicitly indicate the relations and inverses.
• fix store import import Store from '@ember-data/store'; was just not working, switched to import Store from 'ember-data/store'; (no '@') but that might cause an issue going to v5.3.0. I tried following guides about a requestManager but it's the same thing I got stuck on last time. it's confusing and there are no good examples of how to write custom queries with it.
  I had to add a linter ignore rule because of the rule ember/use-ember-data-rfc-395-imports

Tested a bit, tried almost all routes. It seems to work ok now.
Running through jenkins/cypress to see the result.

Ember upgrade added this, do we need/want this? It's showing extra checks on github, failing on something from ember-rdfa-editor

No major breaking tests, only known flakys
