Fix invalid compat bound

[maleadt]

     Testing DiffEqGPU
ERROR: Could not parse compatibility version spec "7.1.0+1" for dependency `pocl_jll` in "/home/tim/Julia/pkg/DiffEqGPU/test/Project.toml"

As a result of this, CI is massively broken here.

I'm also not sure why such specific compat bounds are used? These prevent e.g. testing on 1.10, despite Project.toml advertising compatibility:

ERROR: Unsatisfiable requirements detected for package Statistics [10745b16]:
 Statistics [10745b16] log:
 ├─possible versions are: 1.10.0 or uninstalled
 └─restricted to versions 1.11.1-1 by project [0891da08] — no versions left

     └─project [0891da08] is fixed to version 0.0.0
