Relative paths for main scenes do not work when exporting a project

[sjdalessandro]

Tested versions

Reproducible in: v4.4.1.stable.mono.official [49a5bc7]

System information

Godot v4.4.1.stable.mono - Ubuntu 22.04.5 LTS 22.04 on Wayland - X11 display driver, Multi-window, 1 monitor - OpenGL 3 (Compatibility) - AMD RS880 (DRM 2.50.0 / 6.5.0-21-generic, LLVM 15.0.7) - AMD Phenom(tm) II X4 945 Processor (4 threads)

Issue description

A project exported to Android gets an incorrect path when the main scene path in project.godot is relative, such as:

$ cat project.godot
[...]
run/main_scene="main.tscn"
[...]

Now, the relevant part of the generated project.binary file looks like this:

[...]
00000140: 0000 0400 0000 0900 0000 706f 6e67 2e74  ..........main.t
00000150: 7363 6e00 0000 1b00 0000 6170 706c 6963  scn.......applic
[...]

And when you run the app, it attempts to open main.tscn in the root directory:

$ adb logcat -s godot
[...]
06-22 01:19:11.737 20936 21044 E godot   : ERROR: Cannot open file '/main.tscn'.
06-22 01:19:11.737 20936 21044 E godot   :    at: load (scene/resources/resource_format_text.cpp:1388)
[...]

Steps to reproduce

• Create a new project
• Create a scene
• Save the scene as main.tscn
• Open the project.godot file in a text editor
• Change the main path to run/main_scene="main.tscn"
• Return to the Godot editor.
• Reload the project.godot file from disk when prompted.
• Export your project.

I can't reproduce this when exporting to Linux. So probably platform related.
