### Apache Airflow version

main (development)

### What happened

Currently `extra_links` is a cached property that returns a list without any order since set is used. Since we have 3 links per operator this order gets shuffled during webserver restarts as reported by users. It would be good to have this sorted so that the order is predictable. This is already done in extra_links Airflow API output

### What you think should happen instead

extra link order should be predictable

### How to reproduce

1. Create an operator with 3 or more extra links.
2. Render the links in UI. 
3. Restart the webserver and check the extra link order.
