Add --staged option

[utsavsomaiya]

Why

As a developer, I often juggle multiple tasks. For example, while working on my branch xyz, I was asked to fix an urgent issue. Instead of stashing my changes, I switched branches to address it quickly. After making the fix, I wanted to run Laravel Pint and PHPStan to check for issues, but I needed to focus only on the staged changes.

Currently, there’s a --dirty flag, but I propose adding a --staged flag. This would allow us to run Pint exclusively on staged files, improving our workflow when context-switching.

alias pint-staged="vendor/bin/pint $(git diff --cached --name-only --diff-filter=ACM)"

I have created this alias to run Pint on staged files. This command lets me quickly validate staged changes without affecting uncommitted work. But after this PR merge, I will remove it from .zshrc.

Thanks for your pull request to Laravel!

Unfortunately, I'm going to delay merging this code for now. To preserve our ability to adequately maintain the framework, we need to be very careful regarding the amount of code we include.

If applicable, please consider releasing your code as a package so that the community can still take advantage of your contributions!
