yampa: Relax version bounds on deepseq. Refs #280.

Yampa fails to compile with GHC 9.8, due to a constraint in the cabal
file requiring deepseq < 1.5.0.0, when the version included with GHC 9.8
is precisely 1.5.0.0.

This commit relaxes the upper version bound on deepseq. With that
constraint relaxed, Yampa compiles with GHC 9.8.1
