CLOSES BES-87

BES-87 Refactor the action

• Rename parameters
• Review the defaults
• Provide better descriptions in action.yml

Defaults:

out: 'out'
interfaces_dir: 'solidity/interfaces'
contracts_dir: 'solidity/contracts'
typing_type: 'interfaces'

Can we figure destination_dir from the parameters provided by the user? It's basically some directory + package_name + typing_type

Refactor:

• rename typing_type
• remove _dir from out_dir, interfaces_dir, contracts_dir, destination_dir
• params in createPackages and createPackage are named differently, what's exportDir?
• Make sure export / destination / out naming is applied consistently without mix ups. Maybe there is a better way to name those things?
• Why is there createPackages at all? We transfer its logic to createPackage and reduce the complexity of the action.

Notes:

• The logic to copy each interface or contract and its respective ABI was moved to a single function copySolidityFile since the logic was the same
• The sampleInterfaceName was removed from createReadme function since I think it didn't provide much value and it forced to the copySolidityFile function to return a name which I think is not worth it. Used a hardcoded interface on the usage example inside the README - I can undo that change if it needed
• The README will be updated in another PR

Idea: Instead of exporting the interfaces ABIs as default, could we have an if for each exportType?
If the user wants to only export the interfaces he can set interfaces as argument. If he wants to export only the contracts he can set contracts. If he wants both, he could set all.
By this way, we wouldn't be forcing to export the interfaces if the user only wants to export contracts

👍🏻 added this to Linear to think about later.
