fix: very_good test does not generate coverage in Dart Frog

[AnnaPS]

Description

Trying to run very_good test --coverage --min-coverage 100 results in the following.

Finally, I get the coverage report using the following command:

dart test --coverage=coverage && dart pub global run coverage:format_coverage --lcov --in=coverage --out=coverage/lcov.info --packages=.dart_tool/package_config.json --report-on=routes && genhtml ./coverage/lcov.info -o coverage --dark-mode && open ./coverage/index.html

Thanks to @alestiago for helping me with this command.

Steps To Reproduce

1- Open a new terminal at the root of the project.
2- Run very_good test --coverage --min-coverage 100

Expected Behavior

It would be nice to have the ability to run a very_good test command to get coverage on a Dart Frog project.
