About the repo location

[chenrui333]

👋 Looks like https://scm.osdn.net/gitroot/jnethack is not getting the latest tag vs this github repo, maybe removing its reference (https://osdn.jp/projects/jnethack/) in the repo desc? Thanks!

Also just curious is there any reason why the repo name carries with -alpha in it?

relates to https://github.com/Homebrew/homebrew-core/pull/153272
