Description: 

Previously the generated templates for field_instance, field_instance_widget_settings & field_formatter_settings migrations used different keys. With changes in the FieldInstance source plugin, those key names are now different.

Before (8.3.x):

# d7_field_instance.yml
process:
  settings:
    plugin: d7_field_instance_settings
    source:
      - instance_settings
      - widget_settings
      - field_settings
  default_value:
    plugin: d7_field_instance_defaults
    source:
      - default_value
      - widget_settings

# d7_field_instance_widget_settings.yml
process:
  'options/settings':
    plugin: field_instance_widget_settings
    source:
      - 'widget/type'
      - widget_settings

# d7_field_formatter_settings.yml
process:
  "options/label": label
  "options/weight": weight
  "options/type": 
    -
      plugin: static_map
      source: formatter_type
      ...
  "options/settings":
    plugin: default_value
    source: settings
    ...

After (8.4.x)

# d7_field_instance.yml
process:
  settings:
    plugin: d7_field_instance_settings
    source:
      - settings
      - widget
      - field_definition
  default_value:
    plugin: d7_field_instance_defaults
    source:
      - default_value
      - widget

# d7_field_instance_widget_settings.yml
process:
  'options/settings':
    plugin: field_instance_widget_settings
    source:
      - 'widget/type'
      - 'widget/settings'

# d7_field_formatter_settings.yml
process:
  "options/label": 'formatter/label'
  "options/weight": 'formatter/weight'
  "options/type": 
    -
      plugin: static_map
      source: 'formatter/type'
      ...
  "options/settings":
    plugin: default_value
    source: 'formatter/settings'
    ...
