Describe the project you are working on

Game Jam

Describe the problem or limitation you are having in your project

Creating Animations for an AnimatedSprite node is missing the duplicate feature that the rest of the UI has.

Create an AnimatedSprite node and edit its "SpriteFrames".

Above the animations are buttons for [New Animation] and [Remove Animation] but it is missing a [Duplicate Animation]
Right clicking an animation, doesn't bring up a context menu.
The context menu should at least list [Duplicate Animation] and [Remove Animation].

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Some animations are really complicated, which is why there is a dedicated tool to edit them. To have a new animation with just 1 change, you currently have to restart from scratch for each animation which can take a long time for a single animation, let alone if you have to do this 20 times.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

Edit the "SpriteFrames" of an AnimatedSprite and try to open the right click context menu on an Animation. There should be a Duplicate option.

If this enhancement will not be used often, can it be worked around with a few lines of script?

Is there a reason why this should be core and not an add-on in the asset library?

In the Scene Tab, you can right click a node to get a context menu with a Duplicate option.
In the FileSystem Tab, you can right click a file to get a context menu with a Duplicate... option.
In the Animations Tab for AnimatedSprite, you can NOT right click an animation to get a context menu with a Duplicate option.
