build(deps): set transformers below 4.46, waiting on fixes

[anhuong]

Description of the change

The triton fast_kernels are broken in transformers v4.46 due to the changes and the way the patching is done in fms-acceleration described here. In addition, the gradient_accumulation is deteriorated in v4.46 which is fixed in transformers PR which has been merged but not released yet.

In addition, upgrading transformers broke unit tests and is being resolved/discussion in #383.

Thus we will set transformers below v4.46 while we wait for these fixes to go in.
