### Godot version

v4.0.3.stable.official [5222a99f5]

### System information

Win 10

### Issue description

The project converter injects `) #` into asserts to remove the message:

```
    assert(false) #,"Invalid type for gamepad input.")
        assert(action in device_actions) #,"pairs contained action not in controls: %s" % action)
        assert(len(q) == 2) #,"Each pair should have two directions.")
```

The [implementation in project_converter_3_to_4.cpp](https://github.com/godotengine/godot/blob/3695fe5a573678c6491a6a33f19f9329d3256a48/editor/project_converter_3_to_4.cpp#L2021-L2031) comments:

>  assert(speed < 20, str(randi()%10))  ->  assert(speed < 20) #,str(randi()%10))    GDScript - GDScript bug constant message

However, after #62695, asserts are able to have nonconstant messages again. So I think this step should be removed from the project converter.

### Steps to reproduce

1. Write asserts with a message in Godot 3.5
2. Open that project in Godot 4
3. Allow the project converter to run

You can use the assert from the comment:
```
	var speed = 30
	assert(speed < 20, str(randi()%10))
```
Put it in both Godot 3.5 and 4.0. I confirmed that it works in 4.0.3.

### Minimal reproduction project

Repro steps are trivial.
int end = line.size() - 1; // 
	int variable_start = end - 1;
	int start = end - 1;
	bool is_possibly_nodepath = false;
	bool is_valid_nodepath = false;
	while (start >= 0) {
		char32_t character = line[start];
		bool is_variable_char = (character >= 'A' && character <= 'Z') || (character >= 'a' && character <= 'z') || character == '.' || character == '_';
		bool is_nodepath_start = character == '$';
		bool is_nodepath_sep = character == '/';
		if (is_variable_char || is_nodepath_start || is_nodepath_sep) {
			if (start == 0) {
				break;
			} else if (is_nodepath_sep) {
				// 
				is_possibly_nodepath = true;
			} else if (is_nodepath_start) {
				// 
				is_valid_nodepath = true;
				break;
			}
			if (!is_possibly_nodepath) {
				variable_start--;
