Difference with the official 'psf/black@stable' action

[rickstaa]

Now that psf/black#1909 and psf/black#1940 have been merged this action is not trivial anymore. Below I, therefore, documented the difference between this action and the official black action.

	ricks/action-black	psf/black
Action type	docker	composite
fail_on_error argument	✅	❌
is_formatted output var	✅	❌
specify black version	❌	✅

Hello,
Re
What is the goal of the feature fail_on_error ?
By default, psf/black will return the error code of black process unmodified https://github.com/psf/black/blob/e7fb048281a83733f0b162fc7fa85e48044ea9ec/action/main.py#L181.
And by default you will not return an error code https://github.com/rickstaa/action-black/blob/b1c43752f86fe75a86904bb2feeea8661c58a017/entrypoint.sh#L95C1-L97C3.
But you can simply ignore return code in calling context.
You need less than one or two hours to make the code, test it and submit a PR.
Since I'm slightly paranoïd, it appears to me like bread crumbs for someone else to add a pull request that hides error codes by default.
But I may be wrong.
Best regards,
Laurent Lyaudet
