Revitalize CI

[alaendle]

Some remarks:

• Regenerated and manually adapted the workflow yaml haskell-ci.yml(to include influxdb service & allow localhost access from another container). No further changes - so another regeneration should be easy.
• Removed all warnings from cabal check - changes in influxdb.cabal
• Added cabal.haskell.ci to only build documentation (haddock) on newer GHC's (because older haddock versions don't parse newer code)
• Fixed the doctest I have introduced to be more v2 compatible (changes in JSON.hs)
• Avoid -XOverloadedLists - this gives very strange results with ghc 9.4.5 - so changed UDP.hs (to mimic Write.hs)
• Adopted regressions.hs to accept parser failure from different aeson versions.

So I think the change-set is relatively straightforward - and I hope ready to merge.

Before a new release is made we should maybe consider supporting ghc 9.6 (in a new PR)?

Thanks! I'll take a look tonight.

@maoe - I also have ghc-9.6-support in place, but I thought two different PR's might be better, so I started this one first 😉 So if you take a look at it later maybe you also want to merge https://github.com/alaendle/influxdb-haskell/tree/feature/ghc-9.6.

LGTM. Thank you!

Didn't know it's available like this. Nice!

Sorry I missed this comment. Could you please send a PR for that?

Sure, here is the PR for ghc 9.6 #97.
