Obsolete "hello world" page offers obsolete g8 template

[SethTisue]

on Discord today, a user reported that they googled "scala sbt hello world" and the top hit was https://www.scala-sbt.org/1.x/docs/Hello.html

which is an outdated page that points to the outdated sbt/scala-seed.g8 template, which is an old fork that gives you really old sbt and Scala versions

possible resolutions:

• leave the page in place and update the contents
• leave the page in place but replace it with a single sentence directing the user to https://www.scala-sbt.org/1.x/docs/sbt-new-and-Templates.html and/or https://www.scala-sbt.org/1.x/docs/sbt-by-example.html
• replace the page with an HTTP redirect to one of those pages
• remove the page entirely

looking for references to the old template, we see:

% git grep sbt/scala-seed
src/reference/99-Archive/02-Hello.md:\$ sbt new sbt/scala-seed.g8
src/reference/es/00-Getting-Started/02-sbt-by-example.md:\$ sbt new sbt/scala-seed.g8
src/reference/ja/00-Getting-Started/02-sbt-by-example.md:\$ sbt new sbt/scala-seed.g8
src/reference/ja/99-Archive/02-Hello.md:\$ sbt new sbt/scala-seed.g8

so there's also the translations to worry about.

@eed3si9n I'd be happy to a PR a solution if you give me some guidance on what the appropriate solution is. I'm unsure whether the site infrastructure offers redirects, and I'm uncertain if the page needs to somehow be left in place because it's part of historic sbt 0.13 documentation?

There are a ton of redirects in https://github.com/sbt/website/blob/develop/project/Docs.scala#L106.

I am ok with whatever solution. My suggestion probably is direct to sbt-by-example, and then maybe update the page to mention sbt init and/or argument-less sbt new and let the user pick scala/toolkit.local.
