### Godot version

v4.0.3.rc2.official [2ac4e3bb3]

### System information

Windows 10

### Issue description

It seems that joypad button numbers are changed in Godot 4. The Godot 3->4 conversion doesn't change the button numbers.

This Godot 3 Input Map:

It seems that only buttons 0-3 are same in Godot 3 and 4:

### Steps to reproduce

Convert any Godot 3 project having joypad buttons assigned to inputs.

### Minimal reproduction project

int current_line = 1;
	Vector<String> found_renames;
	for (String &line : lines) {
		if (uint64_t(line.length()) <= maximum_line_length) {
			String old_line = line;
			process_gdscript_line(line, reg_container, builtin);
			if (old_line != line) {
				found_renames.append(simple_line_formatter(current_line, old_line, line));
			}
		}
	}
	return found_renames;
}
bool ProjectConverter3To4::contains_function_call(String &line, String function) const {
	// 
	// 
	if (!line.contains(function)) {
		return false;
	}
	int index = line.find(function);
	if (index == 0) {
		return true;
	}
	char32_t previous_char = line.get(index - 1);
	return (previous_char < '0' || previous_char > '9') && (previous_char < 'a' || previous_char > 'z') && (previous_char < 'A' || previous_char > 'Z') && previous_char != '_' && previous_char != '$' && previous_char != '@';
}
, this function should run only on all ".gd" files and also on lines in ".tscn" files which are parts of built-in Scripts.
