pageserver: increase rate limit duration for layer visit log (#8263)

Browse Source 
## Problem
I'd like to keep this in the tree since it might be useful in prod as
well. It's a bit too noisy as is and missing the lsn.

## Summary of changes
Add an lsn field and and increase the rate limit duration.
