Erik Grinaker 84bbe87d60 pageserver: tweak pageserver_layers_per_read histogram resolution (#10847) ...

## Problem

The current `pageserver_layers_per_read` histogram buckets don't
represent the current reality very well. For the percentiles we care
about (e.g. p50 and p99), we often see fairly high read amp, especially
during ingestion, and anything below 4 can be considered very good.
 
## Summary of changes

Change the per-timeline read amp histogram buckets to `[4.0, 8.0, 16.0,
32.0, 64.0, 128.0, 256.0]`.
