Don't print DebugName spam in duplicate components

[janhohenheim]

Objective

• Duplicate components panic like this:

Bundle [...] has duplicate components: [DebugName { name: "bevy_transform::components::transform::Transform" }]

Solution

• Let's make them panic like that:

Bundle [...] has duplicate components: ["bevy_transform::components::transform::Transform"]

Testing

• None, I know the way DebugName is implemented.

Do we ever want that long Debug representation? Instead of just changing it here, it might make sense to manually impl Debug for DebugName in a way that always delegates to Cow<str> as Debug.

I made a PR for this idea: #21870
