s3 exporter: exporter improvements and migration v2 aws sdk (open-tel…

…emetry#36698)

#### Description

With the annoucement of
[eol](https://aws.amazon.com/blogs/developer/announcing-end-of-support-for-aws-sdk-for-go-v1-on-july-31-2025/)
for the aws v1 sdk, this will give the project time to adopt the latest
SDK to provide feedback.

Furthermore, there is also minor code improvements to improve
maintainability.

#### Link to tracking issue

<!--Describe what testing was performed and which tests were added.-->
#### Testing

Included unit tests as part of the changes.

<!--Describe the documentation added.-->
#### Documentation

This is mostly a behaviourally change, and shouldn't have any user
impact but it is worth calling out.
