Linter Failing on docstr_stmt With NotImplementedError

[ogrady]

Hi,

the linter currently handles the old-style docstrings as "not implemented".
While Godot seems to have moved from quote-based docstrings to diamond-based ones, the linter just crashes with a very non-descriptive error:

# foo.gd
"""
hello world!
"""

> gdlint foo.gd

Traceback (most recent call last):

Could this maybe be changed to recommend the user to change quotes to double diamonds? Or even better: fix it to be so?
The unhandled statement kind in this case is docstr_stmt

I had written a small script to do the conversion for us when we migrated from Godot 3.x to 4, if that is any help:

import sys
import re

def fix_file(lines):
    buffer = []
    in_comment = False
    for line in lines:
        if line.strip().startswith('"""'):
            in_comment = not in_comment
        else:
            if in_comment:
                match = re.search(r'^(\s*)(.*)$', line)
                buffer.append('%s## %s\n' % (match.group(1), match.group(2)))
            else:
                buffer.append(line)
    return buffer

def main(args):
    for file in args:
        with open(file, 'r') as rh:
            new_lines = fix_file(rh.readlines())
            with open(file, 'w') as wh:
                wh.writelines(new_lines)

In Godot 4 the docstrings were removed at first and re-added after a few months due to user complaints. I followed the Godot in gdtoolkit and it looks like I forgot to re-add linter support for them while re-adding general support.
