Inconsistent `version.txt` in `torch_ccl_dev_2.8` branch

[saforem2]

For whatever reason, it seems like this commit:

• https://github.com/intel/torch-ccl/commit/c27ded5190a6b115ec68c7a8c28f40cfe7f0a32a:

  diff --git a/version.txt b/version.txt
  index feb74ff..994e3f7 100644
  --- a/version.txt
  +++ b/version.txt
  @@ -1 +1 @@
  -2.7.0+xpu
  +2.8.0+xpu
  

never made it onto the torch_ccl_dev_2.8 branch.

If we look at the intel/torch-ccl/blob/torch_ccl_dev_2.8/version.txt, we see it still has 2.7.0+cpu:
