feat(db): Distinguish async vs sync database drivers using db.driver attribute

[harryautomazione]

Description

Adds db.driver attribute to database spans in sqlalchemy and asyncpg integrations to allow distinguishing between async and sync executions.

Fixes #5463

Why

In performance dashboards or logs, all DB spans appear generically (op: db). This makes it hard to identify when an application accidentally triggers blocking sync DB calls inside an async loop (eg. FastAPI).

How

• SQLAlchemy Integration: Inside _set_db_data, uses conn.engine.dialect.driver (e.g., aiosqlite, asyncpg, psycopg2).
• AsyncPG Integration: Directly sets db.driver to "asyncpg".

Verification Details

Verified locally using an async SQLAlchemy context where the attribute db.driver was successfully populated with "aiosqlite".
