Move fallible ti.task.dag assignment back inside try/except block (#24533)

[ejk43]

It looks like ti.task.dag was originally protected inside try/except, but was moved out at commit 7be87d

This causes the "View Logs in Elasticsearch" option to crash in the Airflow UI

The PR most likely needs to run full matrix of tests because it modifies parts of the core of Airflow. However, committers might decide to merge it quickly and take the risk. If they don't merge it quickly - please rebase it to the latest main at your convenience, or amend the last commit of the PR, and push it with --force-with-lease.

Another good catch. Thanks for the review and commit, I appreciate the detail.

What's the process to get this into main branch from here? Is anything else needed? (first time PR for me)

We generally need two committer reviews to merge a PR, so let’s wait for now.
