Add comment to Blender/FBX import paths in Editor Settings

[MJacred]

the Enabled fields were moved from Editor Settings to Project Settings. There they have comments referring to the import paths in the Editor Settings.

But vice versa is missing.

Therefore, add a reference documentation to the import path field's tooltips in Editor Settings, pointing back to Project Settings boolean flags as part of the Advanced Settings.

It's confusing that these import paths are enabled in Project Settings and just dropped in Editor Settings without explanation about where they are enabled/disabled.

original issue below

### Godot versions

4.0 alpha 12  
4.0 Alpha 13

### System information

Ubuntu 20.04.1

### Issue description

Settings "filesystem/import/fbx/enabled" and "filesystem/import/blender/enabled" (https://github.com/godotengine/godot/blob/master/doc/classes/ProjectSettings.xml)

still seen here: https://github.com/godotengine/godot/issues/63144
(https://github.com/godotengine/godot/commit/1c6148aa86c4a3b8d5c292da69ffacc2f3a46eb8 on Windows  11)

is gone in Alpha 13:

Also did not find them project settings.

Also, I get the `FBX file import is enabled, but no FBX2glTF path is configured. FBX files will not be imported.` warning on project startup. If the documentation is correct, the default value is TRUE, but I cannot check that (without creating a Editor Plugin).

### Steps to reproduce

Create a new empty project or open any existing one.
* enabling the advanced settings in project settings makes no difference (completely restarting editor after toggling also does not help)

### Minimal reproduction project

_No response_

Did you enable advanced settings in the project settings? It won't show up unless you do.

[MJacred]

Yes, I enabled the advanced settings in project settings. Issue is in both modes. Completely restarting editor after toggling also does not help

I haven't updated to alpha 13 yet, but in 12 I see the options in project settings.

[MJacred]

Thanks @KieranCarden, they are stored in project settings… and there they have a description pointing at the Editor Settings. So vice versa should be done and add a reference documentation in Editor Settings, pointing back to Project Settings boolean flags as part of the Advanced Settings.

add a reference documentation in Editor Settings

This was done in #48548, but not all editor settings have documentation yet as some of them are registered too late to be caught by doctool.

[MJacred]

I updated the issue title and description, so it's actually a documentation/description issue.

If you want to work on it just go ahead, issues don't usually get assigned. That said, as Calinou mentioned above:

not all editor settings have documentation yet as some of them are registered too late to be caught by doctool.

This means it isn't as simple as adding a description into the EditorSettings.xml file, some significant work needs to be done. I don't think the "good first issue" label is accurate.
