[BUG] Editor: Duplicated entities are numbered incorrectly

[EzioDCL]

Issue Description:

When duplicating an entity, a number is assigned to the new item to differentiate it from the original. However, successive duplications add additional numbers to the new entities name instead of iterating from the original number resulting in confusing naming conventions.

Tested on 0.11.1.

Tool:

• Editor
• CLI

Steps to reproduce:

1. Open the Scene Editor
2. Create or import any entity to the scene
3. Duplicate the entity using the right click menu or a keyboard shortcut
4. Notice that the new item will include a "_2" at the end of the entity name
5. Duplicate the newly created entity
6. Notice that a "_3" will be added next to the already present "_2" number

See attached video for more details:

Expected behaviour:

Duplicated entities that already have a number at the end of their name should iterate that same number instead of adding additional numbers to the end of the name.

For example:

Entity Name
Entity Name_2
Entity Name_3
Entity Name_4
Entity Name_5

In this situation if I select "Entity Name_3" and duplicate it, the new entity should be named "Entity Name_6".

Current behaviour:

New numbers are added at the end of the entity name each time:

Entity Name
Entity Name_2
Entity Name_2_3
Entity Name_2_3_4
Entity Name_2_3_4_5

Additional Notes:

A possible but less desirable solution would be to keep the first entity selected after duplicating it so the new numbers are based on this one instead. But I would implement this as a workaround only.
