Tuple input for advanced usage

[hanscg]

Perhaps eventually a new major release where we change how all the parameters
are passed could sort it out so that instead we are explicit about the tuples
of directory+tfversion+args instead of trying to match them across three
arrays.

Combining the three parameters into tuples sounds great for more complex cases, but I'm worried that the change will make this action looks too complicated for people using this with simpler cases (e.g checking just one directory with the latest version of Terraform)

Instead of replacing the current input parameters, perhaps we can introduce a new parameter for advanced usage while keeping the existing parameters? This way we don't need to introduce breaking changes either. I'm thinking about something like this (haven't really thought about the naming or whether this is valid):

uses:
   check_tuple: "[ ('path1', 'version1', 'args1'), ('path2, 'version2, 'args2')]"
