Add Junwei Dai as a maintainer

[dbwiddis]

Description

Following the nomination process at https://github.com/opensearch-project/.github/blob/main/RESPONSIBILITIES.md#nomination I have nominated and the other maintainers of flow-framework have voted to invite @junweid62 to be a maintainer and he has graciously accepted the invitation.

Junwei has been integrally involved in the repository for the past eight months, beginning with setting up automation to validate our workflow steps against the OpenSearch API specification. #900 which also involved making contributions to the API Specification for Flow Framework and ML Commons: https://github.com/opensearch-project/opensearch-api-specification/commits?author=junweid62

He also contributed a valuable feature to add a synchronous API for workflow provisioning. #990

He has also simplified and refactored the way the WorkflowRequest was handled, making the code much more logical and maintainable. #952. This completed PRs don’t tell the whole story; he’s also done significant work trying to standardize and simplify the Workflow Requests, even when that work ended up going a different direction thanks to his research.

He’s taken the initiative to review PRs even when he doesn’t get the green check mark (#1098, #995, #911) and has participated in regular repository maintenance as a release manager.
