Bun.file().writer should work with Symbol.dispose

[webdev03]

What is the problem this feature would solve?

Currently, as far as I know, there should be a writer.end() in code using Bun.file once it doesn't need to use the file descriptor. The new using keyword reduces the need for this by automatically calling a function once the variable is out of scope, making code cleaner.

What is the feature you are proposing to solve the problem?

I propose making Bun.file().writer compatible with this new feature.

const file = Bun.file("./example.txt");
{
  using writer = file.writer();
  writer.write("Hi!");
}
// Automatically removes the file descriptor

What alternatives have you considered?
