feat: add support for dbal 4

[d-mitrofanov-v]

Added support for dbal 4, that should fix #79

As it's a breaking change, it probably should go in version 3 of instrumentation-bundle 🤔

---

Note

Update Doctrine DBAL instrumentation/propagation to DBAL 4 APIs and switch DB attributes to new semconv keys.

• Doctrine DBAL (Instrumentation & Propagation):
  • Adjust method signatures to DBAL 4 (quote, exec, lastInsertId, beginTransaction/commit/rollBack now void).
  • Add getServerVersion() passthrough; refine getNativeConnection() return phpdoc.
  • Update drivers to DBAL 4 platform API: use ServerVersionProvider and StaticServerVersionProvider; remove legacy schema-related methods.
• Semantics:
  • Replace TraceAttributes with DbAttributes/NetworkAttributes/ServerAttributes and migrate keys (e.g., db.system.name, db.namespace).
  • Update platform class references (SQLitePlatform).
• Tests: Align expectations with new attribute keys and platform class.
• Composer: Bump doctrine/dbal dev requirement to ^4.0.
