Fix file icon mapping

[wxiaoguang]

Use the file extension mapping from VSCode's extensions. Otherwise js/ts/vba/... files won't get correct icons.

Manually, it doesn't need to update too much.

Just follow the file's syntax. If you'd like to keep the original script, here it is:

<?php
$path = '/Applications/Visual Studio Code.app/Contents/Resources/app/extensions';
$dirs = glob("$path/*", GLOB_ONLYDIR);
$res = [];
foreach ($dirs as $dir) {
    $json = json_decode(file_get_contents("$dir/package.json"), true);
    $key = "pkg:" . basename($dir);
    foreach ($json['contributes']['languages'] ?? [] as $lang) {
        foreach ($lang['extensions'] ?? [] as $ext) {
            $res[$key][$lang['id']][] = $ext;
        }
    }
}
echo json_encode($res, JSON_PRETTY_PRINT);
