Subject: [bug#58000] [PATCH] gnu: Add ghc-9.0.

From: itd <[email-masked]>

* gnu/packages/haskell.scm (ghc-9.0): New variable.
---
Hi,

this patch introduces GHC 9.0.2.  (More recent than the latest GHC in Guix and
prerequisite to build newer GHC releases, to my understanding.)
Please consider applying it.  Thanks!

Regards
itd
