build: fix release notes generation for migrated libraries

- Remove migrated libraries (bigquery, spanner, storage, datastore, logging) from the hardcoded split list in ReleaseNoteGeneration.java to prevent "release not found" crashes.
- Add explicit test dependency on Guava 32.1.3-jre in release-note-generation/pom.xml to fix conflicts with Truth.
- Add version 3.1.0 to exec-maven-plugin in release-note-generation/pom.xml.
- Update ReleaseNoteGenerationTest to expect monorepo links for logging.

Fixes #7466
