Changes

Adds extended request ID to general AWS Attributes under aws.extended_request_id

Merge requirement checklist

• CONTRIBUTING.md guidelines followed.
• Change log entry added, according to the guidelines in When to add a changelog entry.
  • If your PR does not need a change log, start the PR title with [chore]
• schema-next.yaml updated with changes to existing conventions.

[trivikr]

From my understanding, the schema-next.yaml is not required to be changed, as no existing attribute is being updated. This PR adds a new attribute.

Please reference this attribute from AWS spans you expect the attribute to be available on - there are quite a few of them defined here https://github.com/open-telemetry/semantic-conventions/blob/main/model/aws/sdk-spans.yml

Also, is it populated by any instrumentations?

I've been maintaining AWS SDK for JavaScript for 5+ years, and was recently added as component owner of it's OpenTelemetry Instrumentation in open-telemetry/opentelemetry-js-contrib#2557. I plan to add the attribute as soon as it's merged and released in semantic convention.

AWS SDK for Go Observability solution does use it https://github.com/aws/aws-sdk-go-v2/blob/a164d844a90d8b9f86f8cb827b3fef512eabaabf/service/internal/s3shared/metadata_retriever.go#L53

The markdown-link-check either incorrectly checks the link from the logs, or the link might have been down when the test was performed.
