fix: Move 4 modules from batch1 to batch2 to stay under 21 modules

Batch1 had 24 active modules which is at the classrealm conflict
threshold. Moved producer_with_external_contracts, producer_with_restdocs,
producer_with_webtestclient_restdocs, and producer_with_dsl_restdocs
to batch2 to keep batch1 at 20 modules.
