and opensearch modules
- Removed redundant license declarations and outdated properties

## Issue
Cleanup repeating dependencies in pom.xml. Better test assertions and
apidocs/javadoc generation.
## Change
Refactor project structure and remove unused test dependencies.
- Repeating test dependencies like `tinylog`, `awaitility` and others
were removed from various modules and consolidated in the parent module.
This reduction in clutter helps to streamline the testing process.
- A separate `kotlin` profile was created to manage Kotlin-related
configurations and dependencies.
- Upgraded versions of dependencies like `ai-mocks` and `wiremock` were
implemented. Moved to wiremock-standalone (shaded jar) to avoid
potential version conflicts with runtime classes.
- The test changes in `ChatRequestExtensionsTest.kt` partially migrated
from AssertJ to Kotest assertions.
- Updated Dokka plugin configuration

## Change
This pull request includes the following changes to improve project
dependency management:
- Removed unnecessary and redundant Netty dependencies and exclusions.
- Updated and reorganized dependency versions for consistency, including
new BOM imports for Azure SDK, Netty, and Reactor.
- Eliminated AWS SDK v1 dependencies, transitioning to
`software.amazon.awssdk` BOM for better compatibility and reduced
clutter.
- Removed redundant test dependencies like `assertj-core` and `mockito`
across modules, referring to the parent POM.
- Adjusted `kotlinx-coroutines-test` to use JVM-specific artifact and
standardized dependency version variables.
- Refined POM XML formatting for consistency and clarity (`mvn
spotless:apply`)

## Issue
Dependency cycles removed:
[langchain4j-core]->[langchain4j-parent]->[langchain4j-core]
This cycles prevented project fresh project correctly in Jetbrains Idea.
Cyclyc dependency between this repo and [langchain-embeddings
repo](https://github.com/langchain4j/langchain4j-embeddings) should be
fixed separately.
## Change
- Removed dependency cycles: Removed dependencies to project modules
from `langchain4j-parent`/dependencyManagement to avoid cycles. Added
explicit version number for
langchain4j-core,langchain4j,langchain4j-open-ai.
- Introduced `langchain4j-embeddings.version` for explicit dependency on
another repo.
- Added BOM dependencies to parent pom: junit-bom, mockito-bom. Remved
dependencies, defined in BOMs
- junit.version -> 5.11.3
- Upgraded maven-surefire-plugin, maven-failsafe-plugin. **NB! Renovate
bot is needed to do this automatically**
