Generate URI/JSON for a connection from the Airflow Connection UI

### Description Ability to generate the Connection String in either URI or JSON Format from the Connection UX on the Airflow UI. ### Use case/motivation Many a times, have seen Data Engineers struggle with create Connection via the UI, but then struggle to generate the corresponding JSON or URI required to port it to Secret Managers. We have to either go via Astro CLI or Airflow Shell to export the connection in JSON or URI format. The goal is to make it easier for Users to do this via the UI, and make the migration from a Dev Environment to a more organized Prod Environment's Secret Manager much easier by reducing the turnaround time. ### Related issues _No response_ ### Are you willing to submit a PR? - [x] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md)
