Action translate config.yml file into markdown

[RadWolfie]

While we were trying to figure out how come your action isn't working for us. I thought of several possibilities cause of the issue. Turns out none of them were the cause until I have create a separate repository.

From a clone repository of this action repository, is working fine. Using our workflow file and template in the clone repository are also working fine as well. I have narrow down to your action's bug. Your action is reading config.yml file as markdown which broke the process. config.yml file is reserved for github's additional buttons to be render usage.
See RadWolfie#2 for reproduce issue.

Cheers
