FR: Allow the configuration of custom names

Is your feature request related to a problem? Please describe.
no

Describe the solution you'd like
I would like to change the name of an entity within the card configuration (Instead of changing the global name of the entity)
This seems not to work.

Additional context
none

This should work, if it doesn't then there must be a bug. I cannot check it at the moment

It looks like you want to get rid of the "Low Battery" string which is at the end of the name - instead of renaming all entities manually you can use bulk_rename

But as I said the name property should work and should override the original entity name. Will try to validate it on my HA
