fix(build): constrain network package for WINE test compatibility

Adds constraint network <3.2.8.0 specifically for Windows builds
to work around network-3.2.8.0 issues when running tests under
WINE (see haskell/network#604).

This ensures test suites can run successfully in cross-platform
CI environments using WINE for Windows testing.
