N/A.

Describe the solution you'd like
I think you should keep the configuration in a separate file (maybe a file like .github/recent-activity-config.yml) as there are too many inputs and only add config_file as a option in github action inputs which will tell path to the configuration file. I will assign this to my self if you agree with this request and plz help me in the process of doing it.

Describe alternatives you've considered
N/A.

Additional context
Probaly I will use js-yaml as a dependency to do parse the yaml config.
