[entity][entity-cache-adapter-redis] move transformer responsibility

Upgrades knex to 1.x internally. This changes the behavior of `returning` but not in a way that affects how the knex adapter uses it: `returning('*')` behaves the same as before.

This does, however, change the TypeScript declarations for knex, which changed from:
```
 Knex<TRecord extends {} = any, TResult = unknown[]>
```
to:
```
 Knex<TRecord extends {} = any, TResult = Record<string, any>[]>
```
