Update CI configuration

[int-index]

1. Dropped old GHC versions due to this error from haskell-ci:

   No haskell-ci.sh, skipping bash regeneration
   *ERROR* 'tested-with:' specifically refers to unknown 'GHC' versions: 7.0.4, 7.4.2, 7.6.3, 7.8.4, 7.10.3
   Known GHC versions: 8.0.1, 8.0.2, 8.2.1, 8.2.2, 8.4.1, 8.4.2, 8.4.3, 8.4.4, 8.6.1, 8.6.2, 8.6.3, 8.6.4, 8.6.5, 8.8.1, 8.8.2, 8.8.3, 8.8.4, 8.10.1, 8.10.2, 8.10.3, 8.10.4, 8.10.5, 8.10.6, 8.10.7, 9.0.1, 9.0.2, 9.2.1, 9.2.2, 9.2.3, 9.2.4, 9.2.5, 9.2.6, 9.2.7, 9.2.8, 9.4.1, 9.4.2, 9.4.3, 9.4.4, 9.4.5, 9.4.6, 9.4.7, 9.4.8, 9.6.1, 9.6.2, 9.6.3, 9.6.4, 9.6.5, 9.8.1, 9.8.2, 9.10.1
   

2. Run haskell-ci regenerate

The patch in .github/haskell-ci.patch doesn't apply cleanly, will look into it later.

It appears we are affected by haskell-CI/haskell-ci#738, so it would be good to update the generated workflows with haskell-ci >= 0.19.

@sgraf812 I don't see how haskell-ci#738 is relevant. The failing runs are using haskell-ci-0.19.x and are one month old and failing in cabal test step.

make: ../dist/build/happy/happy: No such file or directory
make: *** [Makefile:78: shift01.g.hs] Error 127

The haskell-ci#738 would fail to run at all.

[sgraf812]

I wasn't clear; the failures are over at #281. We need to land this PR in order to fix the situation.

I'm not working on this at the moment, so if someone wants to take over the branch, be my guest.

[sgraf812]

Wow, this [missing-bounds-important] error is absolutely annoying. First, it doesn't tell you the line number or just the file of the violating dependency. And then it appears to even trigger for the testsuite. What on earth?!

It's a bit unfortunate we have to drop support for GHCs older than 8.2, but I don't know enough about the OS support to judge whether this is avoidable. (Perhaps hvr's PPA phased out with Ubuntu 22.04 and it's toomuch work to support GHC 7.0, say, in ghcup.)

[sgraf812]

I think I'll just go ahead and merge this.

Perhaps I'll try to get rid of the complicated .patch setup afterwards.
