lang/hs-hslua-core: Update to 2.3.1

hslua-core-2.3.1 - Released 2023-03-17.
* New module HsLua.Core.Debug: the module provides bindings to a subset of
  functions of the Lua debug interface. Currently the module only exports
  getupvalue and setupvalue, both of which are also re-exported from
  HsLua.Core.

hslua-core-2.3.0 - Released 2023-03-13.
* The functions loadfile, dofile, and dofileTrace now expect the argument
  to be of type Maybe FilePath. The functions load from stdin when the
  argument is Nothing.
* Added setwarnf' for simple warning messgae handling: The built-in method
  of setting a warn function is flexible but not straight-forward to
  use. The new setwarnf' function allows to set a Haskell action as a
  warning hook: the default warning behavior is kept in place, but, in
  addition to the default action, the hook is called on the concatenated
  warning messages. This can be used to plug Lua warnings into an
  application specific Haskell reporting system.
* Export GCManagedState, newGCManagedState, closeGCManagedState, and
  withGCManagedState from HsLua.Core.
