feat(package-manager): migrate from yarn to pnpm

[Javimtib92]

Migration from yarn to pnpm. This migration includes many changes such as:

• Remove afterInstall (yarn plugin) and move husky to prepare script. Disable it in CI/CD using HUSKY=0 env variable.
• Remove yarn config files
• Install dependencies using just install-deps to initialize pnpm-lock.yaml
• Modify .gitignore and .prettierignore
• Modify justfile scripts
• Fix linstaged not respecting ignored files

⚠️ Please checkout to this branch and test it in your system before approving this PR

Husky has never worked in my local environment, I have always had trouble getting the scripts to run. I hope it will work better with these changes. I will reach out to you or the team if I run into problems.
