Good day team, the YUI module 'moodle-core-formchangechecker' has been deprecated. It has been replaced with 'core_form/changechecker'. Please check MDL-69918 for examples of how to fix this deprecation.

The tool_certificate plugin has one usage of this deprecated YUI module:

• 'admin/tool/certificate/amd/src/modal_form.js' on lines 206 to 208, or on https://github.com/moodleworkplace/moodle-tool_certificate/blob/master/amd/src/modal_form.js#L206

Thank you for your attention to this issue.
