Support to set GITHUB_API_URL as input to the action

[vamsi877]

how to pass custom github api url to the action, as it is always using api.github.com to upload the dependency-graph.

It reads the API URL from the actions runtime environment. The runner knows what it should be point at and that is what is being utilized.

I am running action workflow on my enterprise GHES, instead of using my GHES url it is using api.github.com url while submitting the dependency snapshot, see below log trace ...

I cannot reproduce this, I have tested against GHES 3.13 using this action and with no parameters it correctly uploads to the GHES server the findings. I was using v4 of this action.

What version of the action are you using? Have you got any environment variables set that could be impacting the default GitHub server URLs?
