Part of elastic#192910

url_field_formatter functional test was
[skipped](elastic#193293) in Sept 2024.
Instead of removing `.skip`, the entire test should be removed for the
following reasons
1) It does not test dashboard code. The test verifies rendering of
legacy visualize table on a dashboard and discover table (in the
discover app). Both of these are not our area of responsibility.
2) the test case is better covered by unit tests.

(cherry picked from commit 03af622)
