* feat: first things to do

* feat: create tensors for Jina architecture

* fix: use other tensors

* feat: embedding gets results

* fix: fix usage of ALIBI

* fix: clean prints

* fix: do some cleanup unused vars

* fix: revert changes to Makefile and CMakeLists

* fix: revert some changes

* fix: fix small detail

* fix: fix convert formatting

* fix: fix linting and editor

* feat: set proper vocab settings

* fix: JinaBertForMaskedLM registration

* feat: support q_normalization and k_normalization in Jina arch

* feat: handle gpt2 tokenizer with Jina architecture

* feat: example comments in embedding

* feat: rename Jina Bert to Jina Bert V2

* fix: add some changes as per review

* feat: proper KQ_pos for Jina embeddings

* feat: add capacity to load models ES and DE for Spanish

* llama : fix pre-tokenizers

* ggml : full ALiBi support

* ggml : update ggml_soft_max_ext() CUDA, SYCL

* ggml : ggml_flash_attn_ext() support ALiBi (CPU)

* ggml : ggml_flash_attn_ext() support ALiBi (Metal)

* ggml : fix warning
