localstack-v2 require aws sdk 1.x and 2.x

If we define test-containers-localstack-v2-aws-only2.sc as:

using lib "software.amazon.awssdk:auth:2.17.250"
using lib "com.dimafeng::testcontainers-scala-localstack-v2:0.40.10"

import com.dimafeng.testcontainers.LocalStackV2Container

LocalStackV2Container()

then there is compile error:

$ scala-cli test-containers-localstack-v2-aws-only2.sc
Exception in thread "main" java.lang.NoClassDefFoundError: com/amazonaws/auth/AWSCredentials
	at com.dimafeng.testcontainers.LocalStackV2Container.<init>(LocalStackV2Container.scala:14)

When we add dependency to aws 1.x (making test-containers-localstack-v2-aws-1-and-2.sc):

using lib "software.amazon.awssdk:auth:2.17.250"
using lib "com.dimafeng::testcontainers-scala-localstack-v2:0.40.10"

using lib "com.amazonaws:aws-java-sdk-core:1.12.93"

import com.dimafeng.testcontainers.LocalStackV2Container

LocalStackV2Container()

it will compile:

$ scala-cli test-containers-localstack-v2-aws-1-and-2.sc
Compiling project (Scala 3.1.3, JVM)
Compiled project (Scala 3.1.3, JVM)

SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

It is not very intuitive that testcontainers-scala-localstack-v2 requires both AWS sdk major versions to work and I didn't find any information about that.
