Make the edit warning message more user friendly for non-technical users

What I have also noticed is that the link in the message is going to the entity_usage.usage_list route while the local tab is going to the entity.$entity_type_id.entity_usage route. The former does not show the other tabs for the entity and the link opens in a new browser tab making it hard to browse back.

MR adds config fields for the edit and delete warning messages. It also adds two tokens that can be used the display then entity's bundle name and the URL to the usage page for the entity (the version with the tabs).

Patch attached for Composer based workflows.

This would be a nice improvement! #6 works for me on content entities (nodes), but fails on Media entities with:

The construct $entity->type->entity->label() may not be reliable across entity types. The latest change makes use of the entity_type.bundle.info service to fetch the label instead. Back to NR.

Updated patch.
