Add an OPTIONS chunk to Documentation/git-sparse-checkout.txt

[Shaoxuan Yuan <shaoxuan.yuan02@xxxxxxxxx>]

Hi all,

I'm wondering if we could add an OPTIONS chunk to
Documentation/git-sparse-checkout.txt?

Cause when I was skimming through the SYNOPSIS
and it says "git sparse-checkout <subcommand> [<options>]"
but I didn't quite see the options until I read into the COMMANDS.

Perhaps something like this:

OPTIONS

    --[no-]cone

    --[no-]sparse-index

    --stdin

If this is okay to do then I will try to submit a patch later :)
