[Feature-Request] Should be able to check only changed files during CI.

[BiosBoy]

What exactly happened?
Prettier Action checks all the codebase instead of the files which were changed only on the particular commit.

Steps to reproduce the behavior:

    - name: Prettier Action
      uses: creyD/prettier_action@v3.0
      with:
        prettier_version: 1.19.1
        prettier_options: --write **/*.{js,ts,tsx}

What should've happened?
Should be able to check only changed files during CI.

How did it look?
Check the whole codebase instead. Why?

Sorry, don't have much time :(

Note: git diff --name-only HEAD^..HEAD returns a list of changed files in the latest commit

I will try something tomorrow!
