fix: Rename op db to db.query

[sentrivana]

• According to our span ops there is no op called just db, but we're emitting these from django, clickhouse, asyncpg and pymongo. Changing to db.query instead.
• There was also a breadcrumb with type db that's also officially not a supported type, changed it to query.

This is intentionally just on potel-base since it's technically a breaking change.
