### Godot version

v4.0.stable.official [92bee43ad]

### System information

Windows 10

### Issue description

This Godot 3 line

```gdscript
assert(r.hash() == {"a":1, "b":2}.hash())
```

was converted to this:

```gdscript
assert(r.hash() == {"a":1) #,"b":2}.hash())
```

For some reason `) #` is added after `1`.

### Steps to reproduce

Just converting Godot 3 project containing the line to Godot 4.

### Minimal reproduction project

N/A
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;
