Update CUDA requirement from 5.11.0 to 5.11.0, 6.0

[dependabot]

Updates the requirements on CUDA to permit the latest version.

Release notes

Sourced from CUDA's releases.

v6.0.0

CUDA v6.0.0

Diff since v5.11.0

Breaking changes: Ideally none. CUDA.jl has been split into subpackages, which is a major change, so the major version bump is out of caution. Deprecations have been introduced though, e.g., submodules like CUBLAS are now proper packages, cuBLAS.jl.

This release has been identified as a backport. Automated changelogs for backports tend to be wildly incorrect. Therefore, the list of issues and pull requests is hidden.
