[Flaky test] common/test/acceptance/tests/lms/test_lms_problems.py::FormulaProblemRandomizeTest::test_score_reset_after_resetting_problem_*

[timmc-edx]

This test fails intermittently and has been deleted according to the Flaky Test Process in #20870

See docs on how to address flaky tests for why this should be fixed and how to go about it.

3 specific test cases (including 2 ddt variants of the same method) in FormulaProblemRandomizeTest had been intermittently failing for some time. The failures seem to be due to a MathJax exception:

https://cdn.jsdelivr.net/npm/mathjax@2.7.5/MathJax.js?config=TeX-MML-AM_HTMLorMML:0:0: Script error.

The most common failure: acceptance.tests.lms.test_lms_problems.FormulaProblemRandomizeTest.test_score_reset_after_resetting_problem_2__R_1_R_2_R_3__correct__1_1_pointungraded___0_1_pointungraded__

• Failing: https://build.testeng.edx.org/job/edx-platform-bokchoy-pipeline-pr/5518/
• Passing: https://build.testeng.edx.org/job/edx-platform-bokchoy-pipeline-pr/5527/

Other failure derived from the same test method: acceptance.tests.lms.test_lms_problems.FormulaProblemRandomizeTest.test_score_reset_after_resetting_problem_1__R_1_R_2__incorrect__0_1_pointungraded___0_1_pointungraded__

• Failing: https://build.testeng.edx.org/job/edx-platform-bokchoy-pipeline-pr/5492/
• Passing: https://build.testeng.edx.org/job/edx-platform-bokchoy-pipeline-pr/5502/

Similar failure from another method in the same class: acceptance.tests.lms.test_lms_problems.FormulaProblemRandomizeTest.test_reset_problem_after_submission_1__R_1_R_3__incorrect_`

• Failing: https://build.testeng.edx.org/job/edx-platform-bokchoy-pipeline-pr/5513/
• Passing: https://build.testeng.edx.org/job/edx-platform-bokchoy-pipeline-pr/5514/

Closing because this was a bokchoy test, and those had all since been deleted.
