Add cabal 3.6.0.0

https://discourse.haskell.org/t/ann-cabal-3-6-1-0-and-cabal-install-3-6-0-0/3145

https://downloads.haskell.org/~cabal/cabal-install-3.6.0.0/

For me, a ARMv7 release is listed in this link, but it is a 404 at time of writing.

Unofficial bindists are (still) missing, so I did not mark 3.6.0.0 as recommended yet.
