switch from poetry to uv

[mivanit]

NOTE: re-opening #986 but with docs in the name so that the proper tests run

TODOs

• update pyproject.toml
• update makefile
• test everything
• update github actions
  • checks.yml
  • release.yml (changed this, but quite unsure whether what I did is a good idea. needs review for sure)
• update README.md
• update contributing.md
• update .devcontainer/devcontainer.json and .devcontainer/Dockerfile to use uv instead of poetry. not sure how to do this
  • I think in the dockerfile we can probably set rid of installing/updating system python as uv should handle this automatically?
• using uv breaks pip install inside notebooks
  • added a new "notebooks" group for those deps
  • shouldn't we be avoiding using torchtyping, and use jaxtyping instead?
  • shouldn't linters be catching unused imports?

Description

Poetry can be quite slow for dependency resolution and environment setup. uv is much faster and has rapidly become the new standard.

Type of change

• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

Checklist:

• I have commented my code, particularly in hard-to-understand areas
• I have made corresponding changes to the documentation
• My changes generate no new warnings
• I have added tests that prove my fix is effective or that my feature works
• New and existing unit tests pass locally with my changes
• I have not rewritten tests relating to key interfaces which would affect backward compatibility

ok, looks like nearly everything is passing! The few tests still failing:

• Checks / Compatibility Checks (3.10) (pull_request) is failing due to huggingface_hub.errors.HfHubHTTPError: 429 Client Error: Too Many Requests for url: https://huggingface.co/api/models/NeelNanda/Attn_Only_2L512W_C4_Code/tree/main?recursive=True&expand=False so hopefully will work once we re-run the tests
• Checks / Code Checks (pull_request) is still failing, but it's also still failing on dev-3.x

remaining TODOs:

• assistance needed in updating .devcontainer/devcontainer.json and .devcontainer/Dockerfile
• careful review of changes to release.yml would be appreciated
• wait for tests to be passing on dev-3.x, merge into add-uv, and then all tests should pass?

looks like building docs is failing due to a lack of a huggingface token secret?
