post-deployment-script: shorten Actions Runner path

We were running into errors like:

gpg-agent[768]: socket name '/d/actions-runner/_work/git-for-windows-automation/git-for-windows-
automation/home/.gnupg/S.gpg-agent.extra' is too long

By setting the runner path to /a instead of /actions-runner, we resolve
this (and potential future) long path issues, just like GitHub does
themselves for their hosted runners.
