Add AWS resource detector entry points

[abstractOwl]

Description

The AWS resource detectors currently are not picked up when using the new OTEL_EXPERIMENTAL_RESOURCE_DETECTORS environment variable because they are not registered under the opentelemetry_resource_detector entry point.

This PR adds the relevant section to the sdk-aws pyproject.toml file to allow the resource detectors to be used.

Fixes open-telemetry#1861, open-telemetry#2370

Type of change

• New feature (non-breaking change which adds functionality)

How Has This Been Tested?

Added the following line to my Dockerfile in an otel-instrumented test Flask app:

RUN echo "\n\n[opentelemetry_resource_detector]\naws_elastic_beanstalk =
opentelemetry.sdk.extension.aws.resource.beanstalk:AwsBeanstalkResourceDetector"
 >>
/usr/local/lib/python3.12/site-packages/opentelemetry_sdk_extension_aws-2.0.1.dist-info/entry_points.txt

The logs showed that the relevant resource attributes were set:
