fix(strawberry): Prevent AttributeError on missing graphql_span (#4991)

[harryautomazione]

Problem

In the Strawberry integration (SentryAsyncExtension / SentrySyncExtension), hooks like resolve(), on_parse(), and on_validate() access self.graphql_span with the assumption that .on_operation() had already initialized it.
Under some configurations (e.g., cached execution, isolated field-runs, or custom execution paths), .on_operation() might be bypassed, leading to AttributeError: ... has no attribute 'graphql_span'.

Solution

Added defensive getattr(self, "graphql_span", None) checks in those hooks to safely bypass child span creation if the root span was not created. This preserves operation execution and output correctly without crashing the application.

Fixes #4991
