chore: add check_code_format.yml

[vil02]

This PR adds a workflow, which checks the used code formatting (and makes the necessary changes in the currently existing files).

As suggested by @Ramy-Badr-Ahmed in #13, the new workflow uses fprettify. I could not force it to fail, if there are some changes necessary, so I used a fail if needs reformatting approach as in TheAlgorithms/Nim#19.

Beside the indentation size being set to 4, I used the default setting of the fprettify. Please let me know if you prefer other settings.

The failing part works logs for 8663d15.

Adding the debug output -d to fprettify --indent 4 -d --recursive . can help identifiy the styling mismatches by contributors.

Strange... the output does not appear in the actions logs:

• https://github.com/TheAlgorithms/Fortran/actions/runs/11040556555/job/30668810319
• https://github.com/TheAlgorithms/Fortran/actions/runs/11040442388/job/30668440497
• https://github.com/TheAlgorithms/Fortran/actions/runs/11040275300/job/30667876416

EDIT: of course the output is empty... the files are already reformatted. I will use git diff.

I see. -d flag shows differences, no changes made.

I tried it out and it would work with git diff in the failure step:

      - name: Format Fortran files
        run: |          
          fprettify -i 4 --recursive .
      - name: Fail if needs reformatting      
        run: |  
          if [[ $(git status --porcelain) ]]; then            
            echo "please reformat/fprettify these files:"            
            git diff
            exit 1
          else
            echo "All files are properly formatted."
          fi

Let's have another try 🙂

[vil02]

So as mentioned above: the output was empty, because obviously the files were already reformatted. I used git diff.

Now it works as expected, cf. the failing case: https://github.com/TheAlgorithms/Fortran/actions/runs/11045781263/job/30683988597

Yes, it's now very informative 👍
