'check_roles' is not a supported key

Add:

insert_block\config\schema\insert_block.schema.yml

file with the following content:

filter_settings.filter_insert_block:
type: filter
label: 'Insert Block Filter'
mapping:
check_roles:
type: boolean
label: 'Check roles permissions'

I had a problem with openAI ckeditor5 module.
I uninstalled it and all was fine again

Thank you very much.

filter_settings.filter_insert_block:
  type: filter
  label: 'Insert Block Filter'
  mapping:
    check_roles:
      type: boolean
      label: 'Check roles permissions'

Should be like this in config/schema/insert_block.schema.yml

Thanks. The indentation was added to issue fork merge commit.
