bump cardano-crypto-class && ghc

[CarlosLopezDeLara]

This PR does the follwing:

• bumps to cardano-crypto-class-2.2.3.2
• updates CI to run with ghc: ["9.6.7", "9.8.4", "9.10.3", "9.12.2"]
• Adds an exception handling for kes-agent-control and for kes-agent running on Windows)

This is with a kes-agent-control compiled with ghc 9.12.2 without the fix when kes-agent is down:

kes-agent-control -c control.socket  --retry-delay 2000 --retry-attempts 5 info

Connection to agent failed, will try again 5 more times
Connection to agent failed, will try again 4 more times
Connection to agent failed, will try again 3 more times
Connection to agent failed, will try again 2 more times
Connection to agent failed, will try again 1 more time
kes-agent-control: Uncaught exception ghc-internal:GHC.Internal.IO.Exception.IOException:

HasCallStack backtrace:
  ioError, called at libraries/ghc-internal/src/GHC/Internal/Foreign/C/Error.hs:291:5 in ghc-internal:GHC.Internal.Foreign.C.Error

this happens because 9.12.2 now defaults to including a verbose HasCallStack backtrace

And this is with kes-agent compiled with ghc 9.12.2 where we modified ControlMain.hs to catch handle the exception:

kes-agent-control -c control.socket  --retry-delay 2000 --retry-attempts 5 info
