Create wiki pages describing merge team/dev lead tasks

### Overview
We need a wiki page describing merge team/dev lead tasks, to expedite onboarding and increase merge team engagement

### Action Items
- [x] We are currently in the process of moving the old wiki to the new [website-wiki repo](https://github.com/hackforla/website-wiki), so we will not be making any changes or additions to the old wiki at this time. Thus, we will be adding wiki content through a different process now. Read [How to Contribute to the Wiki](https://github.com/hackforla/website/wiki/How-to-Contribute-to-the-Wiki)
- [x] Create a wiki page with the following sections:
- [x] review onboarding prework issues
- [x] review prework issues in progress
- [x] review `2 weeks inactive` issues (excluding prework issues)
- [x] `Questions/In Review` column
- [x] `Help Wanted` review
- [x] `New Issue Approval` review (`ready for merge team` or `ready for dev lead` )
- [x] `ER` column review
