welcomePresentationPiPlanningIMPACT.js update prior PI placeholders and slide 12 date population

[CherrelleTucker]

Description

welcomePresentationPiPlanningIMPACT.js The Key dates for the PI should populate indefinitely into the future, according to the week requested. Instead, once the calculation reaches the end of 2023, the dates look back around to the beginning of the Project Increment in 2023

Implementation Considerations

• new PI dates should be populated in the IMPACT PI calendar prior to presentation generation.
• new placeholder {{FY.Q-1}} to represent PI wrapping up

Deliverables

• [x] PI Wrap Up populates previous PI {{FY.Q-1}} (pg 4)
• [x] PI Achievements populate previous PI {{FY.Q-1}} (pg 5)
• [x] PI Metrics populate previous PI {{FY.Q-1}} (pg 8)
• [x] Slide 12 dates reflect actual dates from IMPACT PI Planning

Dependencies

new PI dates should be populated in the IMPACT PI calendar prior to presentation generation.

Instead of calculating a PI, have scripts read the PI info from the PI calendar https://calendar.google.com/calendar/u/0?cid=Y19lNmU1MzJjZWZjNWRkZmRkN2YzYzcxNWU3YTA3MzI2NjA3Y2QyNDBkOTUxOTkxZjZhNGUzYjg3NjUzZTY3ZWYzQGdyb3VwLmNhbGVuZGFyLmdvb2dsZS5jb20
