Use CKEditor 5's native <ol type> and <ul type> UX

Problem/Motivation

We "solved" the problem of supporting <ol type> and <ul type> by using the SourceEditing functionality for that.

But in CKEditor 5 32.0.0, they've added a native UX for setting the list type:

Which means that rather than having to edit HTML by hand, the content creator can now do that through the UI! But unfortunately, it currently always generates <ol style="list-style-type:SOMETHING"> and <ul style="list-style-type:SOMETHING">, so we cannot use this.

This is blocked on https://github.com/ckeditor/ckeditor5/issues/11615.

It'd also improve the upgrade path because these attributes would no longer have to get set through the SourceEditing functionality.

Steps to reproduce

Proposed resolution

See above.

Remaining tasks

1. Set styles.useAttribute = true per https://github.com/ckeditor/ckeditor5/issues/11615, this ensures the type attribute will be generated instead of a style attribute
2. Expand the
3. Add configuration to \Drupal\ckeditor5\Plugin\CKEditor5Plugin\ListPlugin::buildConfigurationForm(), to allow enabling the type attribute or not
4. Expand the config schema under ckeditor5.plugin.ckeditor5_list in ckeditor5.schema.yml
5. Expand unit test coverage in \Drupal\Tests\ckeditor5\Unit\ListPluginTest
6. Optional: add more configuration to \Drupal\ckeditor5\Plugin\CKEditor5Plugin\ListPlugin::buildConfigurationForm(), to allow configuring which list type attribute values are allowed. (e.g. type="A" for <ol> or type="circle" for <ul>).→ CKEditor 5 does not yet support restricting this to specific types.
