refs https://github.com/matomo-org/matomo/issues/16689 adds information about archive invalidation entries to the informational system check output so we don't need to ask users to run queries. Can help understand archiving issues.
fyi @diosmosis maybe something else be useful too?
fyi I'll merge this for the next RC @diosmosis let me know in case you have any further thoughts on this
Maybe checking the oldest invalidation date might be useful. Otherwise the core:archive logs are probably more useful.
