A mismatch between Godot engine's version and projects' sourcecode version in Godot HTML5 demo projects

[ZhongGuangshen]

Which demo project is affected:
https://godotengine.github.io/godot-demo-projects/

OS/device including version:
HTML5 (tested in Edge130.0.2849.52)

Issue description:
At present, the Godot engine version in the Godot HTML5 demo project(https://godotengine.github.io/godot-demo-projects/) does not match the Godot version of the demo project source code. The Godot engine version in the HTML5 demo is 3.3.3 stable, while the source code for the demo project may be Godot 3.5 or even higher

In a nutshell, the current HTML5 demo is equal to running a project in 3.5 branch (or even higher) using Godot 3.3.3 stable version, therefore, errors in HTML5 are inevitable

In addition, I personally think that the statement in Godot demo projects has some issues because in reality, projects in the Master(4.x) cannot be compiled by Godot 3.3.3 stable at all.

This issue is based on #1125 (comment), and I noticed that a similar problems have been encountered in issue #786 (comment), referring to this issue I mainly tested the project 2.5D Demo With GDScrpit.

In Windows 11, I exported the HTML5 version of 2.5D Demo With GDScrpit under 3.5branch using Godot3.3.3 and used python-m http.server+ http://localhost:8000 to access it locally in Edge, resulting in the same issue of character‘s being unable to move as that in https://godotengine.github.io/godot-demo-projects/misc/2.5d/

in https://godotengine.github.io/godot-demo-projects/misc/2.5d/ The character in the middle cannot move

The characters in the 3.5 branch project exported in stable 3.3.3 version cannot be moved either
