+### Comment a file content

+Thanks to the `filePath` input, a file content can be commented.
+You can either pass an absolute filePath or a relative one that will be by default retrieved from `GITHUB_WORKSPACE`. 
+(Note that if both a `message` and `filePath` are provided, `message` will take precedence.)
