[CI] Change to renderer_short for BASOP coverage test to align with daily tests
The coverage-test-on-main-scheduled fails occasionally due to the long renderer tests being used. If a slower runner takes the job, the timeout of 6 hours is exceeded. To align with the nightly LTV tests, this changes to renderer_short for the coverage test. A slight drop in coverage is expected.
