upgrade NCCL dependency from 2.26.6 to 2.27.7 in easyconfigs for CuPy 13.6.0, OSU-Micro-Benchmarks 7.5, UCC-CUDA 1.3.0 using a 2025a toolchain

[lexming]

(created using eb --new-pr)

We need a newer NCCL to be able to install PyTorch 2.9.1 in 2025a. Given that existing easyconfigs depending on NCCL are few, this change should not cause much trouble.
