Subject: [PATCH] chore: manage the avro-maven-plugin version in the parent

soon-market-sse-api's native build fails on main with

  generated-sources/avsc/contracts/realtime_event.java: cannot find symbol
    symbol: class JsonSchemaParser  location: package org.apache.avro

It declares avro-maven-plugin without a version, and this pom defined
avro-maven-plugin.version = 1.11.3 as a property it never used - there was
no pluginManagement entry at all - so the version floated to the newest
release. Avro 1.12 generates code referencing
org.apache.avro.JsonSchemaParser, which does not exist in the 1.11 runtime
the quarkus bom provides, so the generated sources cannot compile against
their own runtime.

The property is now actually used, which makes codegen and runtime match
exactly - the property that matters, since generated code must only
reference apis the runtime has:

  avro-maven-plugin:1.11.3:schema
  org.apache.avro:avro:jar:1.11.3:compile

Verified end to end: with no version in sse-api's own pom and its submodule
pointed at this change, mvn compile resolves 1.11.3 and succeeds. That is
why the per repo pin in kryptokrauts/soon-market-sse-api#11 was closed in
favour of this.

sse-api is the only consumer that declares the plugin today; the other four
were checked.
