[FLINK-37733] Externalise DynamoDB connector IT Test to E2E test package

Purpose of the change

[FLINK-37733] Externalise DynamoDB connector IT Test to E2E test package

• DynamoDB connector IT Test currently resides in flink-connector-dynamodb package which means:
  • It is inconsistent with other connector package where IT test resides in their own e2e test package.
  • Building the package takes longer as IT test takes time to spin up a docker environment for the test.
  • Github action/workflow does not run the IT test as they are not in e2e test package.
• This is a minor improvement to relocate the IT test into its own e2e test package similar to other connectors

Verifying this change

Please make sure both new and modified tests in this PR follows the conventions defined in our code quality guide: https://flink.apache.org/contributing/code-style-and-quality-common.html#testing

• This change is a trivial rework / code cleanup without any test coverage as it just relocates existing IT test to a new E2E test package
• Verified the e2e test passes as follows:
  • Run mvn clean verify -Prun-end-to-end-tests -DdistDir=/Users/Downloads/flink-1.19.2

Updated this test case as it failed locally when I ran it with Java version 8.0.432-amzn (Corretto) due to Java floating point number precision only accurate up to 6-7 digits decimal place.

we use java11 right?

we use java11 right?

We use Java 8 based on https://repo1.maven.org/maven2/org/apache/flink/flink-connector-parent/1.0.0/flink-connector-parent-1.0.0.pom

Thanks @gguptp I have revisited this and found that I was running the test with java21 locally, once I changed it to java8, the test passed. As such I have reverted changes to this test case. Please take another look
