### 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.
Vector<String> found_renames;
	int current_line = 1;
	for (String &line : lines) {
		if (uint64_t(line.length()) <= maximum_line_length) {
			String old;
			if (line.contains("tool")) {
				old = line;
				line = reg_container.keyword_gdscript_tool.sub(line, "@tool", true);
				if (old != line) {
					found_renames.append(line_formatter(current_line, "tool", "@tool", line));
				}
			}
			if (line.contains("export")) {
				old = line;
				line = reg_container.keyword_gdscript_export_single.sub(line, "$1@export", true);
				if (old != line) {
					found_renames.append(line_formatter(current_line, "export", "@export", line));
				}
			}
			if (line.contains("export")) {
				old = line;
				line = reg_container.keyword_gdscript_export_mutli.sub(line, "@export", true);
				if (old != line) {
					found_renames.append(line_formatter(current_line, "export", "@export", line));
				}

			if (line.contains("onready")) {
				old = line;
