Add an Update Log (to site health?)

[Ipstenu]

As of the last few major releases, WordPress _auto updates_ major releases.

I am 100% for this, however I've found it can be a total pain to try and figure out why someone was updated sometimes. Not to mention people are now getting updates with only the email as a notice, which means sometimes the non-primary admin will find a problem first and have no clue why.

This could be alleviated if we had an update log, possibly in site health, that recorded...

1. When WP was installed (this will allow you to back track "Oh you started on WP 5.9, that means...")
2. When a plugin or theme is updated
3. When WP is updated

That also lets people keep tabs on when things happened if their email is down or they got shunted to spam.

There are a number of plugins that do this, but having it in core allows it to be utilized by web hosts and wp-cli natively.
