Summary
There is an inconsistency for running tests between deployment and running them directly.
When running a deployment there is an option for code coverage formatters which give a number of options, which is great! I like the html format.

But when running apex run test the options are limited


Steps To Reproduce
sf apex run test --test-level RunLocalTests --output-dir temp --synchronous --result-format html --code-coverage
