in overview doc, no output from `zig build --help`

[uvtc]

In https://ziglang.org/learn/overview/, right after, "Let’s have a look at that --help menu", it says to run

zig build --help

but the current master I have (0.16.0-dev.2565+684032671) doesn't yield any output from that command. In fact, I get:

$ zig build --help
info: initialize build.zig template file with 'zig init'
info: see 'zig --help' for more options
error: no build.zig file found, in the current directory or any parent directories

Looks like that the command is now

zig build-exe --help

and has substantially more output than it used to.
