Enhancement- add skip count, total and passing % to karate summary HTML report

[rc2201]

We are using karate.abort() extensively in our project to control the execution of scenarios depending upon the test data pre-requirement, environment limitations etc. Along with this,our runner executes multiple feature files.

Below enhancement to karate summary report would greatly improve our experience with the reporting-

1. Adding the count of skipped scenario.
2. In case of multiple feature files being executed, adding total# to provide total of passed / failed / skipped scenarios. This is already provided on the console.
3. % of passing scenarios.

Attaching the screenshot for refrence.

Hopefully, other karate users will also find these features useful as well.
