deps: upgrade to diffusers 0.14, safetensors 0.3, transformers 4.26, accelerate 0.16 (#2865)

Things to check for in this version:

- `diffusers` cache location is now more consistent with other
huggingface-hub using code (i.e. `transformers`) as of
https://github.com/huggingface/diffusers/pull/2005. I think ultimately
this should make @damian0815 (and other folks with multiple
diffusers-using projects) happier, but it's worth taking a look to make
sure the way @lstein set things up to respect `HF_HOME` is still
functioning as intended.
- I've gone ahead and updated `transformers` to the current version
(4.26), but I have a vague memory that we were holding it back at some
point? Need to look that up and see if that's the case and why.
