fix(apollo): Do not capture failed requests for empty GraphQL errors arrays

[lbloder]

📜 Description

Failed-request detection in the Apollo 3, 4, and 5 integrations now only captures an event when the GraphQL errors array contains at least one entry. Previously the matcher only checked for the opening bracket of an errors array, so a response like {"data": {}, "errors": []} produced a false-positive event.

The detection stays regex-based ("errors"\s*:\s*\[\s*[^\]\s]), tolerant of whitespace and line breaks. Body reading, streaming-response handling, and data collection are unchanged.

Known limitation, unchanged by this PR: a non-empty field named errors nested inside data still matches.

💡 Motivation and Context

• resolves: Do not capture failed Apollo requests for empty GraphQL errors arrays #6194
• resolves: JAVA-758

Follow-up from #6074 (comment)

💚 How did you test it?

• Added one test per integration that executes a query returning a multiline empty errors array and verifies no event is captured. The tests failed before the fix because an event was captured.
• Existing tests with a non-empty errors array continue to verify capture.
• Updated the Apollo 5 body-reading test fixture from {"errors":[]} to a non-empty array, since those tests expect a capture.
• ./gradlew :sentry-apollo-3:check :sentry-apollo-4:check :sentry-apollo-5:check
