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.

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