feat: add shorthand flag for websocket option in command line

[ayanrajpoot10]

Adds a shorthand -ws flag for the existing -websocket probe in httpx, improving usability by providing a shorter, convenient alias for checking websocket support.

Summary by CodeRabbit

• New Features

  • Added a short -ws alias for the --websocket command-line flag to streamline enabling websocket output. This is fully backward-compatible; existing uses of --websocket continue to work.

• Documentation

  • Updated command help and README to include the -ws alias and clarify usage. No functional or runtime behavior changes were introduced.

Poem

I twitch my ears at flags anew,
A tiny hop from “websocket” to “ws” will do.
No burrow reroute, no maze to redraw—
Just shorter paths for paws and claw.
Thump-thump! I cheer this tidy finesse,
Fewer keystrokes, same success.
