Make plugin compatible with 3.13

[gomoripeti]

Adjust to changes in rabbit_exchange_type behaviour

I only modified broker_version_requirements in the Makefile as the bazel files already seem to be updated.

[gomoripeti]

CI tests fail with a bazel error

Error computing the main repository mapping: in module dependency chain <root> -> rabbitmq-server@_ -> rabbitmq_osiris@1.8.1: module not found in registries: rabbitmq_osiris@1.8.1

I would need help to understand and address it

@gomoripeti this change should help rabbitmq/rabbitmq-delayed-message-exchange#251.

[gomoripeti]

great, thanks for the pointer

looking at valid dialyzer/test failures

[gomoripeti]

finally had the time to fix the test failures. this is ready to be reviewed now.

I know this plugin is not really relevant for the RabbitMQ Core Team. Is there anything more I can do to help merging the necessary changes to release a version that supports RabbitMQ 3.13.x?

Hi all, thanks for this work. I would greatly appreciate merging this. It's blocking my ability to upgrade rabbit. 🙏

Now the same thing has to be done for 4.0.x.
