Updates torch to 2.7.0 with cuda 12.8 blackwell support (#2998)

As required by #2962 and
vulnerabilities in torch 2.5.1, this change updates torch to 2.7.0
during the installation of Isaac Lab.

Although inconsistent with Isaac Sim 4.5 (still on torch 2.5.1), Isaac
Lab should work fine with 2.7.0+cu128. This update will also allow us to
have better support for blackwell GPUs.
