Support input parameters using with map key.

[webispy]

Github action support a map of input parameters via the with keyword. Therefore, the checkpatch-action also needs to be modified to support it.

Would this be needed to use the with solution you described in #27 ?

[webispy]

The current checkpatch-action is receiving input values through environment variables, but according to the GitHub Actions guide, input should be received using the with keyword. While it is possible to also support #27 issues using the existing approach, it would be better to support them using the with keyword.

Currently, I haven't started the work and have put it on hold since there hasn't been a request for it. However, if you want the support, I will consider changing the priority of the task.
