[glob] readdir causes EACCES: permission denied, scandir

https://github.com/actions/toolkit/blob/fc005283374f1cea5e03ea1caf959cd9ff12fdc2/packages/glob/src/internal-globber.ts#L142-L145

As you can see from the above snippet, internal-globber.ts doesn't check if the directory is readable before attempting to read it.

There should be a try catch block around that code:

try {
  const childLevel = item.level + 1;
  const childItems = (await fs.promises.readdir(item.path)).map(
    x =>  new SearchState(path.join(item.path, x), childLevel)
  );
  stack.push(...childItems.reverse());
catch (err) {
  if (err.code === 'EACCES') {
    continue;
  }
  throw err;
}

This issue affects the upload-artifacts action, plus I'm sure other actions that depend on this package.

Start in packages/glob/src/internal-globber.ts at lines 142-145, where readdir is called while traversing directories. Verify how permission-denied errors are currently handled, then confirm that EACCES directories are skipped while other errors still propagate; the change should prevent upload-artifacts and other glob users from failing on unreadable directories.
