The "display_id" entity type does not exist.

Attached is a patch, basically:

$params are coming in as an array of [taxonomy_term: myid, view_id: iForget, display_id: page_1]

$param_keys = array_keys($params);
$entity_type = array_pop($param_keys);

Then we are sending display_id as a $entity_type to SqlContentEntityStorage->save() where it throws a white screen of fun.

The proposed patch checks if it is a valid $entity_type before continuing.

I had this issue after an update from core 9.5.8 to 9.5.11 as well. I rerolled the diff patch to remove the empty .DS_Store differ binary.

The MR doesn't provide any changes from the patch in #3. But it helps validate that it still applies in 8.x-1.x.
