Switch from yapf/pylint/isort to ruff

[fsschneider]

This PR updates our codebase to use ruff for linting and formatting, replacing yapf, pylint, and isort. ruff offers the combined functionality of all three tools while being significantly faster.

Previously, running yapf, pylint, and isort locally took ~1m 16s on my workstation.

pylint algoperf && pylint reference_algorithms && pylint prize_qualification_baselines && pylint submission_runner.py && pylint tests && isort . --check --diff && yapf . --diff --recursive

In contrast, running ruff took ~0.14s on my workstation.

ruff check && ruff format --check  

In GitHub Actions, the improvement is less dramatic due to tool installation times, but I observed roughly a 50% reduction in runtime.

Steps

• Use ruff in GitHub Actions.
• Update documentation to use ruff.
• Ensure that the entire codebase conforms to the new ruff code style.

@fsschneider, sorry, there are some merge conflicts after I merged in the dropout refactoring. Could you help resolve the merge conflicts please? I think we just want to accept incoming changes from the dev branch and then reformat them with ruff.

I believe I resolved them now.
Do we have any tests for the dropout refactoring? This would ensure that I didn't break anything.
