### Apache Airflow version

main (development)

### What happened

On the Task Instances table, one can click on `Edit Record` and be directed to a `Edit Task Instance` page. There, if you try to change the state, it will simply not update nor are there any errors in the browser console.

### What you expected to happen

Changes to state should actually update the task instance.

### How to reproduce

Try to use the `Edit Task Instance` page

### Operating System

Mac OSx

### Versions of Apache Airflow Providers

_No response_

### Deployment

Virtualenv installation

### Deployment details

_No response_

### Anything else

This page is redundant, as a user can successfully edit task instance states from the table. Instead of wiring up the correct actions, I say we should just remove the `Edit Task Instance` page entirely.
