chore: Remove references to IOx in docs/comments (#25728)

This removes references to IOx in our docs and comments as when we
started making Monolith last year it was a fork of influxdb_iox.
This was something that we changed in some places, but not all as
time went on. To avoid confusion whenever we more broadly release
this software I've removed references to IOx in our code and docs.
Note however that we still use a lot of IOx code and our system
tables also return iox as part of the name. This is a separate issue
namely #25227. Some things like env vars will also be cleaned up
in #25646

Closes #25662

 The easiest way to do this is to open up a new ticket, describing the changes you plan to make and *why* you plan to make them. Changes that may seem obviously good to you, are not always obvious to everyone else.
 Example of changes where we would encourage up-front communication:
 
-* new IOx features;
+* new InfluxDB 3 features;
 * significant refactors that move code between modules/crates etc;
 * performance improvements involving new concurrency patterns or the use of `unsafe` code;
 * API-breaking changes, or changes that require a data migration;
