chore(text-splitters): bump dependency locks for python 3.14 (#34522)

* Support sentence-transformers optional dep on python 3.14
* Bump some dep locks to use pre-built wheels instead of building them
(murmurhash, cymem, preshed, thinc, srsly, blis)
* Still not possible to use spacy: even though there are wheels
available, spacy depends on Pydantic v1 which doesn't work on Python
3.14.
* Speeds up installation and CI.
