feat!: update for semantic conventions @ v1.10.0

The most notable thing here is that the delta between 1.8.0 and 1.10.0
results in a few fields going away. This will be a breaking change for
anyone who happens to be depending upon these fields:

- `DB_CASSANDRA_KEYSPACE`
- `DB_HBASE_NAMESPACE`

Users should instead use `DB_NAME`, according to
[open-telemetry/opentelemetry-specification#1973](open-telemetry/opentelemetry-specification#1973).

Otherwise, we get the standard deal:

- A plethora of new, exciting fields!
- Reworded explanatory text!

Overall, not a terribly exciting change, but we must often take joy in
the small things, and I choose to do so here!
