 In general you could replace the original action with this one and it should already work (all its supported inputs are also supported in this one):

 ## Guarantees
 
-The objective of this action is to guarantee that for every major Python version starting from `3.7` at least one specific version can be successfully installed on the `...-latest` images using the default architecture.
