execution date is missing from Task Instance tooltip

[renzepost]

Apache Airflow version

main (development)

What happened

It seems this commit has made the task instance execution date disappear from the task instance tooltip completely:

Note the missing Run: <execution date> between Task_id and Run_id.
I think there's a problem with the task instance execution date, because it's always undefined. In an older version of Airflow (2.4.3), I can see that the tooltip always shows the current datetime instead of the actual execution date, which is what the author of the commit identified in the first place I think.

What you think should happen instead

The tooltip should properly show the task instance's execution date, not the current datetime (or nothing). There's a deeper problem here that causes ti.execution_date to be undefined.

How to reproduce

Run the main branch of Airflow, with a simple DAG that finishes a run successfully. Go to the Graph view of a DAG and hover over any completed task with the mouse.

@renzepost You can refer to run_id after manual__ as it's basically the same information as exetution_date which was changed in the PR - #17719

Based on the Slack thread - https://apache-airflow.slack.com/archives/CCWHRNBK7/p1689064000858439

Summary on the thread - Since a user can override the run_id it is not reliable to lean on run_id always, for the same reason we can introduce another field in taskinstancelogical_date which can hold this information and display it in UI.

PR to override run_id - #21851

The task instance is converted to dict using alchemy_to_dict but execution_date is not a column and a proxy to task_instance. So after forming the dict execution_date attribute value can be updated in the dict. I can raise a PR for this.
