the way output to `stdout` in the master tree is weaker

[l1t1]

the old way supports input an argument,but the new way did not suport.

master

hello.zig
const std = @import("std");

pub fn main() !void {
    try std.fs.File.stdout().writeAll("Hello, World!\n");
}

0.14.1

hello.zig
const std = @import("std");

pub fn main() !void {
    const stdout = std.io.getStdOut().writer();
    try stdout.print("Hello, {s}!\n", .{"world"});
}

To use print with stdout, you need to construct a writer like this,

const std = @import("std");

pub fn main() !void {
    var buf: [4096]u8 = undefined;
    var stdout = std.fs.File.stdout().writer(&buf);
    stdout.interface.print("Hello, {s}!\n", .{"world"}) catch return stdout.err.?;
    stdout.interface.flush() catch return stdout.err.?;
}

However, I think the doc/langref/hello.zig could also be improved since File.writeAll is deprecated.
