Add support for double qutoes

[GreenDjango]

Hi, I have a issue with double quotes import. It's only sort by alphabetical order on one blocs like this:

import "package:epicture/services/navigation/navigation_provider.dart";
import "package:epicture/theme.dart";
import "package:flutter/material.dart";
import "package:flutter/services.dart";
import "package:timeago/timeago.dart" as timeago;

And not like this:

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';

import 'package:timeago/timeago.dart' as timeago;

import 'package:epicture/services/navigation/navigation_provider.dart';
import 'package:epicture/theme.dart';

My local config:

{
    "dartimportsorter.sortOnSave": true,
    "dartimportsorter.leaveEmptyLinesBetweenGroups": true,
    "dartimportsorter.matchingRules": [
        {
            "label": "Dart",
            "regex": "^dart:.*$",
            "order": 1,
            "regexFlags": [
                "m"
            ]
        },
        {
            "label": "Flutter",
            "regex": "^package:flutter/.*$",
            "order": 10,
            "regexFlags": [
                "m"
            ]
        },
        {
            "label": "Package imports that are NOT your app",
            "regex": "^package:(?!epicture|openapi_sdk).*$",
            "order": 100,
            "regexFlags": [
                "m"
            ]
        },
        {
            "label": "Everything else",
            "regex": ".*",
            "order": 101,
            "regexFlags": [
                "m"
            ]
        }
    ]
}

I forgot that two types of quote existed! I'm making a release to support double quotes shortly.
