Hard-coded user.email value in Changelog code causes git push failure

[bjanderson70]

Describe the bug
Using sfpowerscript in a GitHub + Jenkins environment fails to push to the "changelog" when using generatechangelog

I can release except error w/ pushing to changeLog ; the internal system I am on checks the user's email (as valid) ... When I dug a bit deeper into this I noticed in changelog/ChangelogImpl.ts:pushChangelogToBranch sets the user.name to "sfpowerscripts" and user.email to "sfpowerscripts@dxscale" ... this is causing the failure.

Customer runs checkemail anytime a push occurs (not possible to disable)

To Reproduce
Steps to reproduce the behavior:
Using the latest DockerImage . Run script (bash) in Jenkins

sfdx sfpowerscripts:orchestrator:release .... --generatechangelog --branchname changelog

Expected behavior
