HTTP Proxy Support

[RedlineTriad]

When using maven-dependency-submission-action this library does not support http_proxy or https_proxy. Breaking self-hosted runners in environments requiring proxy for access to the github api.

Most other github actions libraries seem to handle this implictly.

👋🏻 @RedlineTriad - yeah, that seems kind of surprising to me too.

Would you mind giving me an example snippet of your workflow for the submission action and verifying how you are setting the http_proxy / https_proxy variables for your workflows?

[RedlineTriad]

I used the template workflow, and just used self-hosted runners instead:
https://github.com/actions/starter-workflows/blob/main/ci/maven.yml

And we set http_proxy, https_proxy, and no_proxy env vars using the gha self hosted runners helm chart:
https://github.com/actions/actions-runner-controller/blob/master/charts/gha-runner-scale-set/values.yaml#L28-L37

I hope this helps? @brrygrdn

I have a draft with some notes on how to proceed here, but I wasn't able to finish it during this FR shift. Hopefully @brrygrdn can take this over next week: #90
