Bump the maximum supported Gradle version in integration tests

The kotlin-gradle-plugin-integration-tests module parameterises its tests across a fixed list of Gradle versions. Bumping the maximum requires synchronised edits to a versions table, a Gradle build list, an AGP compatibility matrix, and a compatibility test's when block — all of which must agree. This skill encodes the procedure.

When to use

Trigger on phrasings such as:

• "bump Gradle in tests" / "bump max Gradle"
• "add Gradle X.Y.Z to integration tests"
• "test against the new Gradle X.Y.Z release"
• "update MAX_SUPPORTED Gradle"
• "support Gradle X.Y in KGP integration tests"
