Run flux e2e test group in GHA's local_e2e_tests job

[gfichtenholt]

Description of the change

It seems that at some point, a new flux test group has been added to the /script/e2e_test.sh file, but we have forgotten to add it to the GHA's local_e2e_tests job, so this test group is not being run in the GHA workflow.

I have also took advantage of this PR to simplify the local_e2e_tests GHA job by setting a timeout of 6 minutes for every tests group, instead of having a default of 4 and setting it to 6 for the operator's group to avoid flaky tests.
Benefits

Run all the e2e tests from GHA.

Possible drawbacks

N/A

Thanks Greg.

I think this is an unintentional change - but should go away if you merge main? (I saw @beni0888 fix this in main earlier today - adding the line that your PR is reverting here by accident).

[gfichtenholt]

yes, don't worry about it. I am in a testing phase
