Build out alignment toolkit "package" in Github for POs

[alexpandel]

Brief description of the task

Let's create a central place in the Github wiki to outline our new alignment practices and centralize our alignment toolkit, so that initiative POs and project teams have one central place to go to stay up to date.

To include:

• overarching framing about alignment goals
  • a tl;dr of the practices we'll use to stay in sync 🔒
  • links to each of the pieces of the alignment toolkit 🔒
  • screenshots of the current project board and SO training plan/release calendar

What steps are needed to make it a reality?

• [x] @alexpandel set up Box account so that I can link things in the Github page
• [x] @alexpandel take first pass and share with rest of SD core team for review
• [x] @alexpandel change "Nick & Ed" mentions to "MES leadership" throughout in Box version
• [x] @NAretakis reorganize existing Github wiki to make more sense for how we're planning to work moving forward
• [x] @NAretakis publish alignment toolkit framing 🔒 on Github, and edit further in there if needed
