Focus on improving content health score

[wadepickett]

Dedicate some time to have an impact on improving factors related to the content health score (see the reporting):
1: Improve freshness where I can have the most impact. High traffic, >365 days for example.
2. Nagging doc build validation issues and have the most impact on the freshness where I can.

If I have some time as a priority 2, hit on the asp.net framework repo a bit too.

Per doc manager this is only to be hit after all other current April commitments accomplished, so any extra time left over, I don't hit more from the high priority in backlog, but instead make some progress on this for the repo.

• Freshness: LastReviewed value is showing as 5 years ago. Was published with an update over a year ago. Has somewhat high traffic.
• Tested and works as is, no changes needed. Just updating the ms.date, nothing else needed.
