A jQuery polyfill for event.which is not same as original code

Fix ESLint probrem.
Please review.

Going to leave in review but not 100% it'll be accepted with the eslint ignores.

If this is causing a bug in functional javascript tests, it should probably update the test coverage.

However, this polyfill has a comment which says it can be removed once https://github.com/minkphp/MinkSelenium2Driver/pull/333 lands, and that has been closed for two years, so can it be completely removed now?

Tried removing it and seems to be green, I think we can repurpose this to remove given it's only used in javascript tests for the testing framework itself and is now unnecessary.

catch → changed the visibility of the branch 3500564-a-jquery-polyfill to hidden.

--- a/core/modules/system/tests/modules/jquery_keyevent_polyfill_test/src/Hook/JqueryKeyeventPolyfillTestHooks.php

was in the wrong directory so this wasn't even being loaded since whichever commit led to the mismatch.

Seems pretty straight forward with the removal.
