Migrate to prek

[ulgens]

pre-commit development was stagnant for a while and now there is a strong alternative that's been writen with Rust: https://github.com/j178/prek

prek's readme list its features as

🚀 A single binary with no dependencies, does not require Python or any other runtime.
⚡ About 10x faster than pre-commit and uses only half the disk space.
🔄 Fully compatible with the original pre-commit configurations and hooks.
🏗️ Built-in support for monorepos (i.e. workspace mode).
🐍 Integration with uv for managing Python virtual environments and dependencies.
🛠️ Improved toolchain installations for Python, Node.js, Go, Rust and Ruby, shared between hooks.
📦 Built-in Rust-native implementation of some common hooks.

I tested it with the projects I'm working on and things are working fine, and even better because prek is faster while installing and running the hook dependencies.

We had a small discussion about the issues with pre-commit's maintenance and agreed to give a chance to prek, on Slack.

I tried to implement the simplest config for CI. We can also implement an optimized workflow with UV, similar to this one and shave off a couple more seconds from the runtime but I'm not sure that is necessary.

This line describes pre-commit but appears in a section about prek. The description should be updated to describe prek instead.

Suggested change

	`pre-commit <https://pre-commit.com>`_ is a framework to run hooks written in many languages, and it manages the language toolchain and dependencies for running the hooks.
	`prek <https://prek.j178.dev/>`_ is a tool for running git hooks, similar to pre-commit, but designed to be faster and dependency-free.

This is intentional.

I understand you intentionally left pre-commit sentence here. What's your goal in doing that?

[ulgens]

@pauloxnet That text is from prek's readme. I didn't leave it there, I copied it from https://github.com/j178/prek/blob/ee7110b49bb1aa8d7b3ccee51c5241550cb0aec2/README.md . If this is somehow confusing, I'm open for recommendations.

Apart from this PRs merge status, we can disable pre-commit.ci integration, we have the related workflow already in the repo.

I added a couple of minor comments.
