maintainance issue w.r.t. STM dependency & GHC version compatibility

[justchilling]

Software Transactional Memory is part of GHC boot libraries and is shipped together, coupled with the compiler version.
( i.e. I cannot install another version of it, other than what comes with GHC)

distributed-process has hard dependency (==) on stm 2.4.* which is only available with GHC 8.4.*
from GHC 8.6 onwards, stm 2.5 is shipped. So now to use distributed-process, I'd have to downgrade my GHC, which is problematic.

rejecting: distributed-process-0.7.4 (conflict:
stm==2.5.0.0/installed-2.5.0.0, distributed-process => stm>=2.4 && <2.5)
