Subject: [PATCH] Update Caffeine to 3.2.4, Checkstyle to 10.26.1 and
 audience-annotations to 0.15.1

These are the dependency updates that were blocked on Java 8 support and
listed as follow-ups in #3547 (Mockito 5 was already done with the
TinkerPop 3.8.2 upgrade):

* Caffeine 2.9.3 -> 3.2.4. Caffeine 3 requires Java 11. JanusGraph only
  uses the builder API (maximumSize/maximumWeight, weigher, expireAfterWrite,
  removalListener, executor, recordStats) and Cache methods that are
  unchanged in 3.x; none of the removed APIs (CacheWriter, StatsCounter
  recordEviction variants, CacheStats constructors) are used. Caffeine
  3.2 declares jspecify and error_prone_annotations instead of
  checker-qual, so the now pointless checker-qual exclusion in
  janusgraph-core is dropped and the managed error_prone_annotations is
  raised from 2.30.0 to 2.50.0 to satisfy the enforcer's upper bound rule.
* Checkstyle 9.3 -> 10.26.1 with maven-checkstyle-plugin 3.4.0 -> 3.6.0.
  10.26.1 is the last Checkstyle line that runs on Java 11 (Checkstyle 11+
  requires Java 17, which the Java 11 build lanes cannot use). The inline
  rule set needs no changes and reports zero violations on all modules.
* audience-annotations 0.13.0 -> 0.15.1 (only a managed version for the
  hbase-shaded-client transitive dependency).
