[chore] Add @carsonip as a codeowner for elasticsearchexporter

[carsonip]

Description:

This PR proposes adding @carsonip as a codeowner for the elasticsearch exporter component, being an employee of Elastic and also meeting the codeowner requirements:

• Be a member of the OpenTelemetry organization.
  • https://github.com/orgs/open-telemetry/people?query=carsonip
• (Code Owner Discretion) It is best to have resolved an issue related to the component, contributed directly to the component, and/or review component PRs. How much interaction with the component is required before becoming a Code Owner is up to any existing Code Owners.
  • [exporter/elasticsearch] Update README #32221
  • [exporter/elasticsearch] Add retry.retry_on_status config #32585
  • [exporter/elasticsearch] Replace go-elasticsearch BulkIndexer with go-docappender #32359
