Description of Changes
This PR improves the TestcontainerFieldBeanDefinition for better safety, clarity, and maintainability. The following changes were made:
- Added null checks: Objects.requireNonNull() is used in the constructor to ensure that Field and Container<?> are non-null, preventing potential NullPointerException.
- Enhanced JavaDoc: More detailed class-level and method-level documentation for better understanding and future maintainability.
- Ensured immutability: Marked the container and annotations fields as final to enforce immutability and improve thread safety.
- Clarified bean setup: Simplified the bean class setup and instance supplier definition.
- Improved error handling: Constructor now validates input parameters to avoid runtime issues.
Why is this change useful?
These changes enhance the safety of the TestcontainerFieldBeanDefinition by ensuring null checks and making it more robust through immutability. The code is also easier to maintain and understand due to improved documentation and clearer logic.

What changes do you want to add? You can continue to push changes to your branch if you wish. However, as things stand, we wouldn't accept the changes in ahmedelazab1220:test-container as, IMO, they don't improve the code as the comments are just repeating what the code already says.

@wilkinsona | i need to add clear javaDoc for This class TestcontainerFieldBeanDefinition.java and add some changes on it to ensure non-null values for the field and container to prevent potential NullPointerException like next.
this.container = Objects.requireNonNull(container, "Container must not be null"); this.annotations = MergedAnnotations.from(Objects.requireNonNull(field, "Field must not be null"));

TestcontainerFieldBeanDefinition isn't public API. As such, javadoc isn't required and neither are the assertions for non-null arguments.
Unfortunately, this sort of cosmetic PR isn't a very good use of our time as we have to spend it reviewing the proposal while the benefit to the project is debatable. If you're keen to contribute to open source, I would recommend looking for issues that are labelled as being well-suited to contribution. For example, we have an ideal-for-contribution label in this repository. Other projects use help wanted or similar.

Thank you for your feedback. I understand now that TestcontainerFieldBeanDefinition is internal and that these types of changes aren't required for non-public API.
I appreciate your time in reviewing this, and I'll take your advice to look for issues that are more suitable for contribution, like the ones labeled "ideal-for-contribution."
I'll go ahead and close this PR. Thanks again for the guidance!
