Rename Phi-3-mini-128k-instruct-Q4_0.gguf to Phi-3.1-mini-128k-instruct-Q4_0.gguf

Note: The name "Phi-3.1" is not mentioned anywhere in the original repository at Huggingface, but since Microsoft uploaded a new version in July without changing its model name, publishers of model quants have largely followed the ggml standard and changed the name of their quants from 3.0 to 3.1, so we follow suit. Although that standard also would have denoted to add the parameter count in the model name, we refrain from doing so, in order to keep as much consistency with the original repo and other publishers of quants as possible.
