Handle negated profiles in S3 bucket multi-document YAML files

[ryanjbaxter]

Fixes #3224

[Copilot]

Pull request overview

This PR addresses #3224 by restoring parity between the S3 backend and other backends (native/git) for multi-document YAML handling when spring.config.activate.on-profile uses negation and more complex profile expressions. It extends the S3 YAML document selection logic so documents activated by profile expressions (e.g., !my-profile, profile1 & !profile2) can be included/excluded correctly, and adds regression tests for these scenarios.

Changes:

• Add S3 YAML document matching support for negated/complex spring.config.activate.on-profile expressions using org.springframework.core.env.Profiles.
• Add new AWS S3 repository tests covering negated profiles, multiple negated documents, and complex expressions (including application-directory layout variants).
• Add test YAML fixtures representing multi-document inputs with negated and complex profile expressions.
