Read stdout from a child process

When using Bun.spawn(), the stdout of the child process can be consumed as a ReadableStream via proc.stdout.

const proc = Bun.spawn(["echo", "hello"]);

const output = await proc.stdout.text();
output; // => "hello"

To instead pipe the stdout of the child process to stdout of the parent process, set "inherit".

const proc = Bun.spawn(["echo", "hello"], {
  stdout: "inherit",
});
