PluginNotFoundException: The "svg_image_field_validate_mime_type" plugin does not exist

Problem/Motivation

The latest stable 2.3.3 version does not work with D11, with the extension validator was deprecated, so I need to switch to 2.3.x-dev to use new DeprecationHelper code.

When uploading an SVG file, there is an error that prevents svg upload:

Drupal\Component\Plugin\Exception\PluginNotFoundException: The "svg_image_field_validate_mime_type" plugin does not exist.

Steps to reproduce

- Drupal version: 11.0.8
- SVG Image Field version: latest 2.3.x-dev

Just try to upload an SVG file in a node field. Error 500 occures. Looked at the Recent Log Messages for error description.

Proposed resolution

There may be due to the change of validation plugins in Drupal 11.

Remaining tasks

User interface changes

API changes

Data model changes
