Refactor Autoclose

[EVDOG4LIFE]

What does this PR do?

Breaks down the GH Action to auto close non member PRs to accommodate multiple access tokens. PAT for org membership, and the standard GH_TOKEN secret for commenting on and closing PRs.

Test Plan

1. Created org Evdogs, added myself - modified action to account for that.
2. Refactored workflow, to break down into multiple steps
3. Generated PAT at the Organization level to read membership
4. Generated PR in Fork to validate as non member - Update LICENSE EVDOG4LIFE/sdk-for-go#2
5. Generated PR in Fork as member - Update avatars.go EVDOG4LIFE/sdk-for-go#1
