Subject: [PATCH] [testnet] Manually adjust proxy/server buckets for latencies
 (#3406)

## Motivation

A lot of changes happened in this prometheus code that we didn't
backport (mainly
[#2878](https://github.com/linera-io/linera-protocol/pull/2878)).
Backporting it would be a huge pain, so I'm just gonna change the
buckets manually for now, and when we cut a new testnet we'll have the
proper stuff in

## Proposal

Manually adjust buckets

## Test Plan
