Remove disabled filters from text format configuration

This now needs a small cleanup after 🐛 Consistently sort filter formats to simplify config exports Fixed .
As for the needed update function:filter_post_update_sort_filters() from that issue must be perfect example code.

This will help make 📌 [PP-2] Make FilterFormat config entities fully validatable Postponed simpler.

AFAICT this should also change

# Filter with module and status.
filter:
  type: mapping
  label: 'Filter'
  mapping:
    id:
      type: string
      label: 'ID'
      constraints:
        PluginExists:
          manager: plugin.manager.filter
          interface: 'Drupal\filter\Plugin\FilterInterface'
    provider:
      type: string
      label: 'Provider'
    status:
      type: boolean
      label: 'Status'
    weight:
      type: integer
      label: 'Weight'
    settings:
      type: filter_settings.[%parent.id]

to:

filter:
  type: mapping
  label: 'Filter'
  mapping:
    id:
      type: string
      label: 'ID'
      constraints:
        PluginExists:
          manager: plugin.manager.filter
          interface: 'Drupal\filter\Plugin\FilterInterface'
    provider:
      type: string
      label: 'Provider'
    weight:
      type: integer
      label: 'Weight'
    settings:
      type: filter_settings.[%parent.id]

… because all entries in filter.format.*:filters will have status: true.

Also: \Drupal\ckeditor5\Plugin\CKEditor5PluginManager::isPluginDisabled() can be simplified thanks to this change:
