Wrong paths for examples in README

[cmontemuino]

Following example in https://github.com/com-lihaoyi/mill#sub-process-tests-without-packagingpublishing

./mill "example.basic[1-simple].local"
[61/61] =================================================================================== example.basic[1-simple].local ==================================================================================== 1s
Cannot resolve example.basic[1-simple].local. Try `mill resolve example._` to see what's available.

I've tried with ./mill "example.scalalib.basic[1-simple].local", but I get an error:

[cmontemuino]

It looks like a trivial PR ahead. I just need confirmation the replacement is ./mill "example.fundamentals.cross[1-simple].local"

[lihaoyi]

@cmontemuino let's use ./mill "example.javalib.basic[1-simple].local", but yeah should be an easy fix if you're up for making a PR!
