feat: Add filter by ecosystem (#184)

Good day @kunalnagar,
thank you for your work.

While in our project we have monorepository, we need the feature to run
action for different ecosystems.
I made some changes and it works like a charm.

I know that it's not ready-to-merge PR, but maybe we can prepare it
together? I'm not a JS developer btw :)
