### Godot version

Godot 4.0 Beta 11

### System information

Linux Ubunutu

### Issue description

Godot's 3.x project converter to 4.0 seems to be missing the conversion for two drag data related functions.

In 3.x the function for can drop data, was named  `can_drop_data` in 4.0 it is `_can_drop_data`.
And likewise 3.x had `drop_data` and 4.0 has `_drop_data`.

These two functions were not converted by the project converter (and were hard to notice)!


### Steps to reproduce

Convert a 3.x project to 4.0 with the functions: `can_drop_data` it will not convert to `_can_drop_data` nor `drop_data` to `_drop_data`.
