[BUG]: Missing db.execute for SQLite

### What version of `drizzle-orm` are you using?

0.28.6

### What version of `drizzle-kit` are you using?

0.19.13

### Describe the Bug

The `db.execute` method mentioned in the docs is _not_ implemented, I would expect to find it here `drizzle-orm/drizzle-orm/src/sqlite-core/db.ts`
https://orm.drizzle.team/docs/sql

### Expected behavior

I would expect the `execute` method to be implemented or if it is not planned/possible at least mention it in the docs :)

### Environment & setup

_No response_
