Add ability to get PR creator name, email?

[wi-ry]

I'm trying to find a way to get the name of the PR creator and so far I've had no luck. Here's what I've tried, I always get a blank variable or the name of the person who merged the PR, not created it:

            echo "githubActor: ${{ github.actor }}"
            echo "github.event.issue.user.login: ${{ github.event.issue.user.login }}"
            echo "github.event.pull_request.user.login: ${{ github.event.pull_request.user.login }}"
            echo "github.event.pusher.name: ${{ github.event.pusher.name }}"
            echo "github.event.head_commit.author.name: ${{ github.event.head_commit.author.name }}"
            echo "github.triggering_actor: ${{ github.triggering_actor }}"

githubActor: MrAusnadian
github.event.issue.user.login: 
github.event.pull_request.user.login: 
github.event.pusher.name: MrAusnadian
github.event.head_commit.author.name: Will Ryan
github.triggering_actor: MrAusnadian

For this PR, I'd like to get the name "TheReptileUnknown", not MrAusnadian/Will Ryan:
