Keycloak container consumes too much memory in devmode

Describe the bug

After https://github.com/quarkusio/quarkus/pull/41162 I get tests in Quarkas quickstarts fail with OOM exception inside DevMode containers. This issue can only be reproduced, when modules are run together and not one after another, when using machine with 8GB or less of memory

Expected behavior

Tests should not fail (as in 3.12.0)

Actual behavior

How to Reproduce?

git clone -b development https://github.com/quarkusio/quarkus-quickstarts.git && cd quarkus-quickstarts
mvn clean verify

If run with mvn clean verify -Dquarkus.keycloak.devservices.java-opts="-XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m -XX:+UseParallelGC -XX:GCTimeRatio=4 -XX:AdaptiveSizePolicyWeight=90" or even mvn clean verify -Dquarkus.keycloak.devservices.java-opts="-XX:MaxMetaspaceSize=256m -XX:AdaptiveSizePolicyWeight=90", this doesn't fail

Output of `uname -a` or `ver`
