Grid task logs filtering and local time

[pierrejeambrun]

Follow up of #24249.

Enforcing log parsing to add:

• Local datetime for the logs
• Filter on the log level (DEBUG, INFO, WARNING, etc.)
• Filter on the log group (python logger that emitted the log).

The parsing function is quite light at the moment, I still decided to memoized the results as I assume this could become quite expensive if the user requests the log full_content.

I also moved moment initialization for tests from testUtils to jest-setup.js. (Sometimes tests don't need a wrapper, and we still have to import testUtils module to get moment defined)

Tested with mapped tasks and task group. ✔️

Let's at least set a minWidth to the file dropdown to the default text doesn't get cut off.
Let's set a fixed with to the log level dropdown, so it too doesn't move around.

Great work! I think people will be really excited for all of this!

The PR is likely OK to be merged with just subset of tests for default Python and Database versions without running the full matrix of tests, because it does not modify the core of Airflow. If the committers decide that the full tests matrix is needed, they will add the label 'full tests needed'. Then you should rebase to the latest main or amend the last commit of the PR, and push it with --force-with-lease.
