Remove min version requirement for rocThrust

It was introduced in ROCm 3.9 days. We now depend on Kokkos 4, which
requires ROCm 5.2.

This requiement also breaks compiling with ROCm 6, as rocThrust has
SameMajorVersion CMake compatibility mode instead of AnyNewerVersion,
and rocThrust coming with ROCm6 has version 3.x.
