[later phase] Default props values may introduce additional config dependencies

Here's a patch that updates the existing test coverage to use the text field type instead of the string field type and it does not cause a test failure. That proves that Component::calculateDependencies() is missing some additional logic.

As the issue summary says: Look at how Drupal's existing Field UI handles this.

FYI: I marked this for a later phase because this is IMHO low-risk. It's a known TODO, with a known solution, in Drupal core.

Sibling follow-up issue 📌 [PP-1] Default props values should support files/images Postponed is much riskier, so is not marked for a later phase.

✨ Allow specifying default props values when opting an SDC in for XB Fixed is in.

Sibling issue: 📌 `StringSemanticsConstraint::MARKUP`: agree how SDC prop JSON schema can convey it should be markup, and Needs review .

If #3467959-35: SDC and code component props should be able to receive HTML, editable in CKEditor 5 → is considered acceptable, we won't have to deal with the FilterFormat scenario described in this issue.

But … the root problem remains. See the example of XB's image SDC:

uuid: 1574ac0a-b1b6-4b32-aaef-a15c18d95aa0
langcode: en
status: true
dependencies:
  module:
    - media_library
label: Image
id: sdc.experience_builder.image
provider: experience_builder
source: sdc
category: Other
settings:
  plugin_id: 'experience_builder:image'
  prop_field_definitions:
    image:
      field_type: entity_reference
      field_storage_settings:
        target_type: media
      field_instance_settings:
        handler: 'default:media'
        handler_settings:
          target_bundles:
            image: image
      field_widget: media_library_widget
      default_value: {  }
      expression: 'ℹ︎entity_reference␟{src↝entity␜␜entity:media:image␝field_media_image␞␟entity␜␜entity:file␝uri␞␟url,alt↝entity␜␜entity:media:image␝field_media_image␞␟alt,width↝entity␜␜entity:media:image␝field_media_image␞␟width,height↝entity␜␜entity:media:image␝field_media_image␞␟height}'

… while this contains

dependencies:
  module:
    - media_library

That is inadequate, it should have:

dependencies:
  config:
    - media.type.image
  module:
    - media_library

(due to its field_instance_settings)

IOW: \Drupal\experience_builder\Plugin\ExperienceBuilder\ComponentSource\GeneratedFieldExplicitInputUxComponentSourceBase::calculateDependencies() must be updated.
