Adopt new GHC support policy
The README claimed a minimum supported version of GHC 8.4.x, but that no
longer matched reality. While fixing the GHC < 9.8 build issues in #781
I checked which versions xmobar actually builds with, and the oldest
that succeeds is 9.2:
- GHC 8.4/8.6 fail because colour-2.3.6 requires base >= 4.13 (i.e.
GHC >= 8.8).
- GHC 8.8/8.10/9.0 fail because Xmobar.Plugins.Accordion uses GHC APIs
they lack (withFileBlocking, hGetContents').
Rather than add compatibility shims to keep claiming support for
versions upstream itself no longer recommends, #784 settled on a
simpler, sustainable policy: officially support only the GHC versions
upstream marks as `Suitable for use` in the GHC status overview
(https://gitlab.haskell.org/ghc/ghc/-/wikis/GHC-Status). At the time of
writing that means 9.6 through 9.14.
This commit implements that policy:
- Bump the lower bound on base to >= 4.18 (GHC 9.6) so the build
constraints match the documented support, instead of silently
failing on older compilers.
- Document the policy and the current 9.6-9.14 range in the README,
replacing the stale 8.4.x note.
Users who need older GHC versions can continue to use older xmobar
releases.
