📝 Docs: Clarify CMake version requirement for CUDA dialects

Adds a note explaining that default CMake versions on systems like
Ubuntu 22.04 LTS might not support newer CUDA dialects (e.g., CUDA 20),
leading to specific build errors.

Recommends installing a newer CMake via the Kitware APT repository
as a resolution. This helps users troubleshoot errors like:
"Target ... requires the language dialect 'CUDA20', but CMake does not know the compile flags..."

+- **Note**: The default CMake version in Ubuntu 22.04 LTS or higher may not support newer CUDA language dialects (e.g., CUDA 20). This can cause errors such as Target "cmTC_xxxxxx" requires the language dialect "CUDA20", but CMake does not know the compile flags to use to enable it. To resolve this, install a newer CMake version, for instance, by adding the Kitware APT repository.
