Inconsistent capitalization of default scene file names

System information

recently updated arch linux

Issue description

When saving a new scene for the first time the default name (without extension) is the name of the root node of that scene but starting with a lowercase letter (even when the root node starts with an uppercase letter).

When saving a branch as a scene and the root of that branch starts with an uppercase letter, the default filename is the name of that branch root as it is, so with an uppercase letter.

I would expect the proposed default filename to be more consistent

Steps to reproduce

• Create a new project
• Create a root node called Main
• Save this scene. It will show main.tscn as default filename
• Create a child node called Player
• Save the Player branch as a scene. It will show Player.tscn as default filename.

Note that #41991 addresses this for scripts, but not for scenes.

The option to change default casing was added in #52597
Seems like it's just not applied in all cases.

Hi, I'm new and I'd like to try working on this.
I've had a look and it looks like the enum used for the cases is private in editor_node.h.
Would making it public be a good idea?

Would making it public be a good idea?

Making the enum public sounds fine to fine.

[KoBeWi]

If making it public is really necessary then yes.

It would be nice that while fixing this you could also make it respect the choice in Project Settings... master currently doesn't and just defaults to snake case even if you choose one of the other 2 options

Hey, new to the scene and I'm just trying to understand.
In keeping with what's outlined in the docs, we want ALL scene tree nodes' file names to be snake case?
Also keen to give this issue a shot!
