Godot 4.5 documentation/completion in hot-reloading not working; but also works?

### Godot version

4.5.stable.official.876b29033

### godot-cpp version

4.5

### System information

Archlinux, Intel Core i3-3245, Integrated Graphics. Wayland with Hyprland

### Issue description

After upgrading my project from **v4.4.1** to **v4.5**, I re-dumped the extension API and interface, then recompiled it. Everything worked as expected, the GDExtension runs correctly when running the project.

However, when I modify the GDExtension and recompile it **while the editor is running**, the documentation and code completions related to the GDExtension stop working. It's as if the editor doesn’t reload the extension.

Even so, running the project still works. Also, if I relaunch the editor, the documentation and completions work again.

The issue only occurs when recompiling the GDExtension while the editor is running, then documentation and completions suddenly stop working.

I tried the same process with **godot-cpp-template**, using Godot 4.5 and upgrading the template. The same thing happens: after compiling the GDExtension, documentation and completion disappear.

### Steps to reproduce

I made a fork of godot-cpp-template.

```sh
git clone https://github.com/NexushasTaken/godot-cpp-template.git -b issue
cd godot-cpp-template
scons target=template_debug debug_symbols=yes use_hot_reload=yes generate_bindings=yes use_llvm=yes build_library=yes platform=linux
```

open godot
```sh
godot --path demo -e
```
Try running the project; it should work.

Next, on the issue, **do not relaunch the editor**.

Just add new simple methods using `ClassDB::bind_method` in `ExampleClass::_bind_methods`.

on `ExampleClass::_bind_methods`:
```cpp
ClassDB::bind_method(D_METHOD("foobar"), &ExampleClass::foobar);
```

bottom of the `example_class.cpp` file:
```cpp
void ExampleClass::foobar() {
print_line("Hello from foobar()");
}
```

In the ExampleClass:
```cpp
void foobar();
```

Recompile the gdextension using:
```sh
scons target=template_debug debug_symbols=yes use_hot_reload=yes generate_bindings=yes use_llvm=yes build_library=yes platform=linux
```

And go to the editor, the documentation and completion shouldn't work, but running the project will work.
