Remove stale JSON inline test and fix CI failure

The testJsonInlineChunkedResults_withoutArrow test and its WireMock recordings
used JSON_ARRAY format which no longer matches driver requests now that Arrow
is always enabled. Remove the test and recordings — chunked Arrow results are
covered by MultiChunkExecutionIntegrationTests and
SqlExecApiHybridResultsIntegrationTests.

Also restructure BREAKING CHANGES section in NEXT_CHANGELOG.md with
sub-sections for Metadata JDBC Spec Compliance and Default Behavior Changes.
