CI is terribly outdated

I was trying to fix a CI on macOS/stack and went here for advice, but I found that CI tests only GHC 8.10 and openssl@1.1 which are both quite outdated now:

HsOpenSSL/.github/workflows/haskell.yml

Lines 18 to 24 in 05118c0

	ghc: ["8.10.7"]
	os: [ubuntu-latest, macos-latest, windows-latest]
	env:
	# OpenSSL is installed in a non-standard location in MacOS. See
	# https://github.com/actions/virtual-environments/blob/main/images/macos/macos-latest-Readme.md
	PKG_CONFIG_PATH: ${{ (matrix.os == 'macos-latest' && '/usr/lib/pkgconfig:/usr/local/opt/openssl@1.1/lib/pkgconfig') || (matrix.os == 'ubuntu-latest' && '/usr/lib/pkgconfig:/usr/local/lib/pkgconfig') || '' }}

@vshabanov : I think it is important to have a CI that covers a wide range of GHC versions and some contemporary setups. (E.g. how about GHC 9?)

E.g. I am getting build failures for HsOpenSSL here, but without HsOpenSSL having a working CI itself, it is tedious to investigate this: https://github.com/haskell-hvr/http-io-streams/actions/runs/9734337346/job/26862232728?pr=20

HsOpenSSL current promises to support GHC >= 7.10 (base >= 4.8), but where is the evidence for this? Usually CI should deliver the evidence.
