The update to convert "numeric" arguments to "entity_target_id" is deprecated

Added the fix as a MR for 3.0.x.

Added a patch for 2.x for who might need it in their workflow.

hm... Then we have the same issue with other views? We have 10 occurrences of plugin_id: numeric in the current codebase?

We need a update_hook_N similar to what was done in https://git.drupalcode.org/project/commerce/-/merge_requests/300/diffs#8... to update views on existing commerce instances if they were not customized by site admin.

As discussed on Slack, let's check how core handled this, and let's open a followup issue for the update hook.

Committed the patch so the views are at least correct on news installs, but we still need to take care of the update hook.
